Memecoin trading terms: the complete glossary
Memecoin trading has its own vocabulary, half borrowed from decentralised finance and half invented on Crypto Twitter. This glossary defines 67 memecoin trading terms in plain language, alphabetically, with a note on why each matters. Where a term means something specific inside the fomo app, the entry says so.
The Solana meme coins on the fomo app guide covers discovery and rug checks in depth, and the meme coin profit calculator turns slippage, liquidity and fees into numbers.
A
Airdrop
Free tokens sent to wallets, usually to reward early users or holders of another coin. Many are junk tokens that appear uninvited, and interacting with those can be a phishing route.
Ape / aping
Buying a coin fast with little or no research, usually because it is moving. “I aped in” means the trader bought first and thought later.
ATH (all-time high)
The highest price a token has ever traded at. Buying near ATH means every existing holder is in profit and has a reason to sell to you.
B
Bag / bagholder
A bag is a position in a token. A bagholder is someone still holding after the price has collapsed. “Holding the bag” is not a compliment.
Base
An Ethereum layer 2 network built by Coinbase and the second-biggest home for meme coins after Solana. fomo supports it alongside Solana, BNB Chain, Ethereum, Monad and Robinhood Chain from one balance.
Bonding curve
A pricing formula used by launchpads like pump.fun. Instead of a liquidity pool, the contract sets each buyer’s price from how many tokens have already been sold, so price rises with every purchase. The coin stays on the curve until it graduates.
Bridge
A service that moves assets from one blockchain to another, often slowly and with its own fees and hack history. fomo advertises one balance across chains with no bridging.
Bundle
A launch where the creator buys a large share of supply across many wallets in the same block, so the holder list looks spread out when one person controls it. Bundled coins can be dumped on buyers at any time.
Burn
Sending tokens or LP tokens to an address nobody controls. Burned LP means the creator cannot pull the pool. Burned supply cuts the total token count.
C
CA (contract address)
The unique on-chain address of a token. Names and tickers can be copied; the CA cannot. Trade by the CA, and be suspicious of any coin shared without one.
CEX (centralised exchange)
An exchange run by a company that holds your funds, such as Coinbase. Most meme coins never list on one, and a listing rumour is a classic pump trigger.
Copy trading
Automatically mirroring another trader’s buys and sells. fomo lets you follow traders for alerts and its FAQ discusses copy trading, but the exact in-app mechanics (one-tap copy, auto-copy, sizing) are not documented publicly. See fomo app copy trading for what is known.
Cross-chain
Anything that works across more than one blockchain. A cross-chain swap sells a token on one chain and buys on another in one step. fomo’s web app announcement lists cross-chain swaps across Solana, Base, BNB Chain and Monad.
D
Degen
Short for degenerate. A trader who takes very high-risk positions on purpose and knows it. Said with pride on Crypto Twitter and as a warning everywhere else.
Dev wallet
The wallet of the person who created a token. Its share of supply and its recent transactions say more about a coin’s future than the chart does.
DEX (decentralised exchange)
An exchange that runs as smart contracts on a blockchain, trading against liquidity pools instead of a company-run order book. Raydium and Uniswap are examples. Meme coins live on DEXs.
Diamond hands
Holding through big drops without selling. Sometimes discipline, sometimes denial. The phrase gets used to shame people out of selling, which benefits whoever wants to sell first.
DYOR (do your own research)
A disclaimer attached to nearly every shill. It means the poster takes no responsibility if you buy. Treat it as an instruction.
E
Exit liquidity
The buyers who let earlier holders sell at a profit. If you buy a coin after it has already run, you are probably someone else’s exit liquidity. This is the most useful concept on the page.
F
Fair launch
A launch with no presale and no insider allocation, where everyone buys from the same starting point. Often claimed, less often true. Bundles are the usual way it is faked.
FDV (fully diluted valuation)
Token price multiplied by total supply, including tokens not yet circulating. When FDV sits far above market cap, a lot of supply is waiting to hit the market.
FOMO (fear of missing out)
The feeling behind most bad memecoin entries: a coin is climbing and you buy because you cannot stand watching. The fomo app is named after it.
G
Gas
The fee a blockchain charges to process a transaction. Tiny on Solana, sometimes large on Ethereum. fomo includes gas in its trading fee.
Gasless
A user experience where you never hold a separate gas token or see a gas line item. fomo describes itself this way: the fee you see already covers gas.
Graduation
The moment a bonding curve coin hits its launchpad’s threshold and gets moved into a real DEX liquidity pool. After graduation the coin has a pool, real liquidity and a market cap that means something. Most coins never get there.
H
Holder count
The number of wallets holding a token. A high count spread evenly is healthier than one where the top ten wallets hold most of the supply. Check the distribution as well as the number.
Honeypot
A token whose contract lets you buy but blocks or heavily taxes selling. You watch the price rise and cannot get out. Trade histories with buys and no sells are the tell.
I
Isolated margin
A perps setting where only the margin assigned to one position can be lost on liquidation, rather than your whole account. fomo’s perps use isolated margin and are not available to U.S. persons.
J
Jeet
Slang for someone who sells early or at the first sign of trouble. Used as an insult by people who wanted you to keep holding.
K
KOL (key opinion leader)
An influencer with enough followers to move a coin’s price by posting about it. Many are paid to post, and some hold bags they plan to sell into the attention they create.
L
Launchpad
A site where anyone can create a token in minutes, usually on a bonding curve. pump.fun is the largest on Solana. Launching a coin happens here rather than inside trading apps like fomo.
Leaderboard
A ranking of traders by profit. fomo has a leaderboard of profitable traders you can follow for alerts. Past profit does not predict future profit.
Leverage
Borrowing to trade a larger position than your balance. At 10x, a 10% move against you wipes the position. Available on perps only.
Limit order
An order to buy or sell at a set price or better, which waits until the market reaches it. fomo confirms take profit and stop loss on perps; whether limit orders exist on spot is something to check inside the app.
Liquidation
When a leveraged position loses enough that the exchange closes it automatically. On perps, liquidation means the margin for that position is gone.
Liquidity
The value in a token’s DEX pool, which is what your buys and sells trade against. Low liquidity means big price moves on small trades and trouble getting out. Compare it with market cap before buying.
Liquidity lock
Placing LP tokens in a time-locked contract so the creator cannot remove the pool for a set period. Locked or burned liquidity removes one common rug method, though not all of them.
LP (liquidity pool / liquidity provider)
The pool of two tokens (say, SOL and the meme coin) that a DEX trades against, or the person who deposited into it. Whoever holds the LP tokens can withdraw the pool, which is why locked and burned LP matter.
M
Market cap
Price multiplied by circulating supply. Traders quote it more than price because a coin at $0.0001 tells you nothing until you know how many tokens exist. “Entered at 200K mcap” is the standard way to describe a buy.
Market order
An order that fills immediately at the best available price. Every quick buy on a memecoin app is a market order, and slippage is what you pay for the speed.
Meme coin
A token with no product or revenue whose value comes from attention, community and jokes. Dogecoin was the first. Most new ones go to zero; that is the base rate rather than a criticism.
MEV (maximal extractable value)
Profit that bots and validators extract by reordering or inserting transactions around yours, most often by sandwiching your buy so you pay more. fomo routes trades through DFlow for MEV protection.
Mint authority
The permission to create new tokens of a coin. If the creator has not revoked it, they can print more and dilute every holder. Revoked mint authority is one of the first checks worth doing.
Moon
A huge price increase. “Mooning” means going up fast; “to the moon” is the wish. Nobody who says it can tell you when it stops.
N
Narrative
The story that makes a group of coins move together: AI agents, a celebrity, a political event, an animal. Narratives rotate fast, and being late to one is where most losses come from.
O
On-chain
Recorded on the blockchain itself, where anyone can verify it. Holder lists, trade histories and liquidity are all on-chain.
P
Paper hands
Selling at the first dip. The opposite of diamond hands, and often the smarter move on a meme coin. Used to mock people who took profit.
Perps (perpetual futures)
Derivative contracts that track an asset’s price with leverage and no expiry. fomo launched perps in June 2026, powered by Hyperliquid and Trade[XYZ], covering crypto, US equities, indices and commodities. Not available to U.S. persons.
PnL (profit and loss)
How much a position or account is up or down. Unrealised PnL is on paper; realised PnL is what you have after selling. On thin meme coins the two differ, because selling moves the price.
Pump and dump
A coordinated push to raise a coin’s price on hype, followed by the organisers selling into the buyers they attracted. Most memecoin “calls” in group chats are some version of this.
pump.fun
The largest Solana launchpad, where anyone can create a token on a bonding curve in minutes. Coins graduate from pump.fun to a DEX pool once they hit its threshold, and that is when they show up in apps like fomo.
Q
Quick buy
A one-tap purchase with a preset amount and slippage, built to shorten the gap between seeing a coin and owning it. fomo has quick buy in its feed. Speed is also how people buy coins they never checked.
R
Rug pull
When the people behind a coin drain its liquidity or dump their supply, leaving holders with tokens that cannot be sold at any meaningful price. Most checks in this glossary exist to spot one ahead of time.
S
Self-custody
A wallet model where you hold the keys to your funds instead of a company. fomo uses a self-custody wallet powered by Privy, with no seed phrase and login by email code or Apple ID. Nobody can freeze your funds, and nobody can recover them for you if you sign a bad transaction.
Shill
Promoting a coin, often while holding a bag or being paid to. Not always dishonest, but the incentive is always there.
Slippage
The difference between the price you expected and the price you got, caused by your own trade moving the pool. Apps let you set a tolerance; too low and trades fail, too high and you overpay. The profit calculator estimates it from pool liquidity.
Sniper
A bot or trader that buys in the first block of a launch, before humans can react, then sells into the buyers who follow. Buy a coin seconds after launch and you are buying from snipers.
Stop loss
An order that sells automatically if price falls to a level you set. fomo confirms stop loss on perps; for spot meme coins, check the sell screen. The stop loss on the fomo app guide covers what is confirmed.
Supply
The total number of tokens. Circulating supply is what is tradable now; total supply includes locked, vesting or unminted tokens. The gap is why FDV and market cap differ.
T
Take profit
An order that sells automatically once price rises to a level you set. Confirmed on fomo perps. On spot, writing your target down before you buy is the manual version.
Thesis
On fomo, a thesis is a trader’s written argument for why they hold a coin, posted on the coin page with their position visible. It beats a one-line shill because you can see whether the author still holds and read the replies. It is still one person’s opinion.
Ticker
The short symbol for a token, like SOL or a meme coin’s four-letter name. Tickers are not unique, which is why the contract address is what you verify.
Token tax
A percentage the contract takes from every buy or sell, paid to the creator or a treasury. Some are disclosed; a hidden high sell tax is a soft honeypot.
Trending
A list of tokens with the most current activity by volume, buys or mentions. fomo has an in-app trending list. Trending tables on other sites, including this one, come from public DEX data and show what the market is chasing, which is often the moment to be careful.
V
Volume
The total value traded in a period, usually 24 hours. High volume with flat price means buyers and sellers are fighting. High volume on a tiny holder count can mean one bot washing trades to fake interest.
W
Wallet
The software that holds your keys and signs your transactions. On fomo, the wallet is created at signup and holds one balance across every supported chain. The address is public; the key that controls it is what you protect.
Whale
A holder large enough to move a coin’s price alone. A whale selling into a thin pool can crash it in one transaction, which is why top holder share matters.
Whatever app you use, liquidity, holder share, mint authority and your own position size decide most outcomes. fomo charges about 0.45% per spot trade with gas included; the fomo app fees page shows what that costs on a round trip. Meme coins are high-risk speculation, most people lose money trading them, and nothing here is financial advice.
