"O" Terms

ot
Street
Out of town to sell drugs — running supply somewhere far from home turf where the prices are higher and the competition thinner. UK county-lines lingo that crossed the Atlantic.
ot3
Internet
A polyamorous ship of three characters a fan supports as a group; extends to OT4, OT5, etc.
ot7
Internet
Short for 'One True Seven,' describing a fan who supports every member of a group without a single bias. The number matches the group's size, so OT8, OT9, etc. exist.
ota
General
OTA stands for Open To All. Most ballroom categories are gendered — they're for butch queens, or femme queens, or butches — but an OTA category drops the gate. Any gender identity, any expression, everybody walks the same floor and competes head to head. It's the category that levels the room, and it's grown into its own mini-ball series with both mainstream and Kiki editions.
otaku
Internet
A person with a consuming obsession for anime, manga, gaming, or any niche hobby. In Japanese it can describe any super-fan, but in the West it almost always means an anime fan.
otb
General
Short for 'over the bars', describing being thrown forward off the bike past the handlebars in a crash. It is used as both a noun and a warning.
ote
Street
Used to describe an original, unadulterated product as opposed to a fake or knock-off, common in market trading contexts.
otilo
Street
Popularised by dancer Poco Lee; expresses that something has completely run out, ended, or been depleted.
otm
Internet
'Out of the money': an option whose strike is unfavorable to the underlying's current price, so it holds only time value. Cheap OTM calls are WSB lottery tickets.
otokonoko
Internet
A male character with a feminine gender expression or who cross-dresses, often indistinguishable in appearance from a girl. A distinct and gentler cousin of the contested 'trap' label.
otome game
Internet
A story-driven video game marketed to a female audience, in which the player pursues romantic relationships with a cast of male characters.
otp
Internet
Stands for 'One True Pairing.' Your ultimate ship — the romantic pairing you'd put above all others in a fandom. People will scream OTP about anything from canon couples to two characters who've shared three lines of dialogue. Variants OT3, OT4, OT5 etc. extend it to polyamorous groupings (common in K-pop, where OT7 means 'all seven members together forever').
otter
General
A slim or wiry gay man who's still got the body hair. Same fur as a bear, smaller frame. He'd be a bear if he bulked up, but the lean build earns him his own slot in the menagerie.
ottoke
Internet
An exclamation of helplessness or panic meaning 'what do I do?' Idols use it in cute or overwhelmed moments.
otw
Internet
Stands for "on the way," indicating you or something is en route. Similar to OMW.
ouf
General
Used as a hype intensifier meaning amazing, insane, or off the chain, like English 'sick' or 'mad'.
our kid
General
Your younger brother (or sometimes sister), used affectionately.
our wench
General
Affectionate Brummie term for one's sister, or sometimes a daughter or close female relative. 'Wench' kept its older neutral meaning of 'girl' in the Midlands long after it turned pejorative elsewhere. Paired with 'our' (as in 'our kid'), it's pure warmth.
out
General
A procedure word meaning "this is the end of my transmission and no answer is required or expected." Contrary to Hollywood usage, 'over and out' is technically contradictory and improper.
out of bounds
Gaming
A glitched state where you clip through the map and end up outside the intended playable area. Runners use it to skip whole sections by walking through the void behind the level.
out of pocket
Internet
Behaviour that crosses a line — said something it shouldn't, did something unhinged, brought up the wrong topic. Tone is usually amused-shocked rather than genuinely angry.
outback
General
The vast, remote and arid interior of Australia, more remote than 'the bush'.
outdoor
General
An off-licence. Called an 'outdoor' because drink is bought to be consumed outdoors, away from the pub.
outer boroughs
General
Brooklyn, Queens, the Bronx, and Staten Island collectively — everything that isn't Manhattan.
outlawed
General
When a trucker has run out their federally mandated Hours-of-Service clock and any further driving would be illegal. You're not a criminal — you're just one mile past the limit and now legally parked until your reset.
outside
Street
Out in the world having fun, going to events and being social.
outside the wire
General
Anywhere past the protected boundary of a base, where enemy contact is possible.
outstanding

Acting wildly inappropriate, disrespectful, or over the top.
outta sight
Music
Excellent, amazing, or wonderful to a remarkable degree.
outwith
General
Outside of or beyond. Standard in Scottish English where others would say 'outside of'.
ova
Internet
An Original Video Animation — an anime episode or series released straight to home video (VHS, DVD, Blu-ray) rather than airing on television or in theatres. Often used for bonus stories or higher-budget one-offs.
ova by
Street
Pure Yat. In New Orleans you don't go 'to' your mamma's, you go 'ova by' her house. It collapses 'over by' into one word and stands in for 'at' or 'to' depending on the sentence. A dead giveaway you grew up below I-10.
ovah
General
A drawn-out, emphatic 'over,' shouted when something is so good it's beyond, over the top, astonishing the room. It's both an adjective ('that look is ovah') and a flat-out exclamation. Top-tier praise in the ballroom; you don't say it lightly.
ovah / over
General
So good it's gone past good, ovah means beyond, the absolute top. Interchangeable with cunty or sickening, sometimes nudging toward legendary. When a performance or a look is ovah, there's nowhere higher to go.
over
General
A procedure word signalling "this is the end of my transmission to you and a response is necessary." It hands the channel to the other station and invites them to transmit.
over 9000
Internet
A hyperbolic stand-in for 'a stupidly large amount.' Slap it on anything you want to flag as off-the-charts: power, hype, calories, your phone bill. Always read in Vegeta's strangled shout for full effect.
over the falls
General
A wipeout where the surfer is sucked up the face and thrown over with the falling lip in a violent circular motion.
over the hump
Street
Reaching the halfway mark of one's sentence, after which the remaining time feels like downhill.
over yonder
General
A directional phrase pointing to a place away from the speaker, typically accompanied by a nod or gesture; "way over yonder" adds distance.
overbought
Internet
An asset is overbought when it has risen sharply and, by momentum indicators like RSI above 70, may be overextended and vulnerable to a pullback. It suggests buying pressure has gotten ahead of itself.
overemployed
Internet
A money strategy enabled by remote work.
overhaul
General
The phase after the main knockdown where crews pull ceilings, open walls, flip mattresses and chase smouldering pockets to make sure the fire is genuinely out. Sweaty, filthy, and where most of the carcinogen exposure happens — full SCBA still on.
overhead
General
Describes a wave whose face is taller than a standing person, used as a rough measure of wave size.
overnight
General
Extended engagement covering dinner, sex and actually sharing the bed until morning. Vetting is stricter than for a one-hour call, the rate is a flat package, and providers usually cap how many they'll take per month because they wreck your sleep schedule.
oversold
Internet
An asset is oversold when it has dropped sharply and, by indicators like RSI below 30, may be overextended to the downside and due for a bounce. It suggests selling pressure has been excessive.
overstand
General
To understand — Rastas replace 'under' with 'over' to avoid negative connotations, so one rises to knowledge rather than standing under it.
