Latest slang terms

seethe
Internet
To be visibly bitter or furious, typically about missing gains, being wrong, or watching a coin you sold pump. Often paired with 'cope'.
seen
Street
An affirmation meaning 'I see', 'I understand' or 'agreed'; also used as a question 'seen?' ('you get it?').
seems legit
Internet
Deadpan reaction to something that very obviously is not legit — a sketchy anonymous founder, a token promising 10,000% APY, a 'Dubai-based' project with a stock-photo team page. The phrase does all the lifting; no further analysis needed.
seeing-eye single
General
A slow or softly hit ground ball that, as if it had eyes, finds a gap between infielders and rolls into the outfield for a base hit.
seed phrase
Internet
A human-readable list of words that encodes a wallet's private key; anyone with it controls the funds, so it must never be shared.
secure the bag
Street
To get paid or close out a money-making opportunity — the literal act of getting your money before it slips away.
secure
General
In naval and Marine usage, to stop or cease an activity, or to put something away and lock it up. 'Secure from work' ends the workday.
section

A part of a wave that breaks as its own segment; surfers race, make or get caught behind a 'section'.
secret sauce
General
The proprietary ingredient, method, or advantage that makes a company or product special.
secondary

The secondary market where NFTs are bought and sold after the primary mint, e.g. on OpenSea; where floor prices and royalties play out.
seat cover
General
An attractive female passenger or driver in a nearby car — called out over the CB so the next driver knows to look. Old-school trucker slang from when the CB was basically a rolling group chat. Says a lot about the era it comes from.
seasoning
Street
The process of heating and coating a new quartz banger with concentrate to condition it and improve flavor before regular use.
seasonal
Internet
Refers to anime currently airing in one of the year's four broadcast seasons (winter, spring, summer, fall). Fans build 'seasonal' watch lists of the shows running that quarter.
seam ripper
Internet
A pointed hand tool used to unpick stitches, essential for altering costumes and for deconstructing wigs to remove or move wefts.
sealioning
Internet
Pretending to debate in good faith while actually grinding someone down. The sealion asks for citations, definitions, and 'just one more example' until the target either snaps or logs off, at which point the sealion claims victory for being so reasonable.
seagull
General
Slang for a senior clinician (often a consultant or 'flying' specialist) who appears briefly, criticises loudly, changes everything, then departs leaving others to clear up.

A tale or yarn calculated to impress listeners, usually stretched well past the truth — the naval cousin of a tall tale.
sea cat
General
The Caribbean term for squid or octopus.
sea bath
General
A trip to bathe in the ocean, often for health or leisure, a beloved Bajan ritual.
sdi
Gaming
Different beast from regular DI. During the freeze frames of a hit (hitlag), rapid stick inputs shove your character a little in that direction. Stack enough and you can wiggle out of a multi-hit move before the finisher connects.
sdcc
Internet
The common initialism for San Diego Comic-Con International, one of the largest and most prominent pop-culture conventions in the world.
scuttlebutt
General
Word on the deck. Unofficial info passed sailor to sailor, Marine to Marine — the kind that's usually half-wrong but spreads at light speed. Promotion lists, deployment rumours, who's getting relieved, who slept with whose wife. None of it confirmed; all of it discussed.
scuttered
General
Drunk. Not tipsy, not merry — properly gone. The kind of drunk where you're slurring, swaying, and explaining your feelings to a stranger at the bar. A staple of Irish pub vocabulary.
scut
General
A contemptible or useless person; can also be a mischievous rascal. 'Scutting' means hitching a dangerous ride on a vehicle.
