Latest slang terms

food
Street
'Food' is drugs — usually whatever the line is pushing that week. The logic is simple: it's what puts dinner on the table. To 'serve food' is to sell, to 'whip food' is to cook crack.
foo-fool
General
Extremely foolish, silly, or easily fooled; the doubling intensifies the meaning.
fomo candle
Internet
A large green candlestick produced when a wave of buyers piles in out of fear of missing the move.
fomo
Internet
The anxiety that drives people to buy an asset as it rallies, afraid of missing further gains. A powerful and often costly emotional trading trigger.
foley
General
The standard indwelling bladder catheter — flexible tube with an inflatable balloon at the tip to hold it in place. Universal hospital shorthand: nurses, surgeons and ER staff all just say 'Foley' instead of the full mouthful. Named after Frederic Foley, the American urologist who designed it in the 1930s.
fok
General
An order that demands immediate, complete execution. If the full size can't trade in one shot the moment it hits the book, the whole thing dies. AON's impatient cousin — AON will sit and wait, FOK won't.
foin
General
Figuratively, to palm or slip something in or out by trickery; the root of the later 'foist upon'.
foh
General
The guest-facing half of the operation: servers, runners, bussers, hosts, sommeliers, bartenders, managers on the floor. Tipped, on stage, and judged on charm as much as competence.
foenem
Street
Your tight circle — homies, gang, the people riding with you. 'Folks' is Chicago shorthand tied to Folk Nation affiliations, and 'nem' just means 'and them'. Together it covers the squad you'd take a charge for.
focus fire
Gaming
Everyone shoots the same target at once. Doesn't matter if you spread your aim across three enemies and tickle them all. Pick one, melt it, move to the next. Five guns on one body wins the trade.
focus
Gaming
Coordinating everyone to attack the same enemy at once, usually the carry or a key target, so it dies before it can do anything. Spreading damage loses fights; focus wins them.
fobbit
General
A soldier who stays inside the wire of the Forward Operating Base (FOB) and does not go outside on missions, implying they have not seen real combat.
fob
General
'Forward Operating Base' — a secured forward military position used to support tactical operations, typically with defenses, logistics, and command facilities.
fo shizzle
Music
Means 'for sure' or 'absolutely,' rendered in the playful -izzle slang.
flying the coop
General
Driving straight past an open weigh station instead of pulling in like you're supposed to. Big fines if you get caught, and DOT will often radio ahead to a chase car. Sometimes done when you're overweight, out of hours, or just running hot.
flyin' horses
Street
What New Orleans kids call a carousel. The name belongs first to the 1906 wooden carousel in City Park's Carousel Gardens — one of only a hundred-odd antique wooden carousels left in the country — but locals use it for any merry-go-round.
fly off the handle
General
To erupt in anger without warning, like an axe head flying loose.
fly girl
Music
A fashionable, attractive, and self-assured woman, especially one tied to hip-hop style.
fly cup
General
A sneaky, between-meals cup of tea — usually with a biscuit, scone, or cake. The 'fly' bit isn't about flies; it's the older Scots sense of 'sly' or 'on the quiet'. A wee guilty pleasure brew.
fly cop
Street
A 'fly cop' (or 'elbow') is a plainclothes police detective, 'fly' meaning sharp or cunning.
flush
General
To throw down a dunk cleanly and forcefully.
fluid overload
General
A state of excess circulating fluid, common in heart or renal failure, causing oedema and breathlessness. Everyday clinical shorthand for hypervolaemia.
fluffy
General
Sneaky hospital euphemism for severely obese — soft enough to slip into earshot or notes without flagging anything, mean enough to count as derogatory slang in the ethics literature. Sits in the same family as 'Milwaukee goiter' and gets the same critique: it shapes how staff treat the patient before they've said a word.
fluffernutter
General
White bread, peanut butter on one slice, Marshmallow Fluff on the other, smash together. A New England school-lunch staple, invented essentially the moment Fluff existed (Lynn, MA, early 1900s). The name was coined in a 1960 ad campaign and Massachusetts made it the state sandwich in 2024.
