"O" Slang

oic

General

'Officer In Charge' — the officer designated as responsible for a particular activity, detail, or facility, often a smaller or temporary scope than a formal command.

ojou-sama

Internet

A well-bred, affluent young lady character — often haughty, sheltered and elegant, sometimes with a signature aristocratic laugh ('ohohoho'). A recognisable stock archetype.

ok boomer

Internet

A short, smiling kiss-off used to dismiss a take perceived as out-of-touch, condescending, or generationally entitled — usually from a baby boomer, but applied to anyone giving boomer-energy. The whole point is refusing to debate.

okizeme

Gaming

The setups you run on a downed opponent as they wake up, meaties, throws, mix-ups, designed so they have to guess right or eat damage the moment they stand.

ol'talk

General

Casual conversation, gossip or persuasive patter, central to a good lime. Also old-talk.

old bill

General

The police, especially in London. Often just 'the Bill'. Origin is fuzzy — possibly the WWI cartoon character Old Bill, possibly the 'BL' on old Met warrant cards. ITV's The Bill ran for 26 years and locked it into the national vocabulary.

old guard

General

The Old Guard is leather culture's founding myth — the period from roughly the end of WWII to the late 1960s, when gay leather circles ran on tight clubs, rigid protocol and a borrowed-from-the-military chain of command. Honorifics were mandatory, ranks were earned, and everything had a rule. Worth knowing: historians treat the 'returning WWII vets built it' story as more legend than verified fact — no single person actually fits the whole tale. But the romance of it still shapes how a lot of leather people talk about 'how it used to be done.'

old man's friend

General

Traditional epithet for pneumonia, historically regarded as a relatively peaceful cause of death in the very old and frail.

old mate

General

A stand-in reference for a person whose name you don't know or won't say; tone can be neutral or scornful.

old money

Pop

The traditional sense — families who have been wealthy for generations, as opposed to the newly rich.

old nat

Street

Old National Highway, the long commercial strip running through College Park and south Fulton County. Constant lyric drop in Atlanta rap — strip clubs, shops, motels and the rougher reputation that goes with it. Place-code for the south side.

old natty

Street

Atlanta shorthand for Old National Highway, the corridor running through south Fulton/College Park. Name-dropped constantly in ATL rap as a marker of southside roots — gritty, lived-in, not the tourist Atlanta.

old way

General

Old Way is the original vogue style, the one that ruled before 1990. It's all about clean lines, symmetry, precision and controlled transitions — graceful, fluid poses snapped into place with total discipline. The visual references are Egyptian hieroglyphs and high-fashion editorial poses, so it reads almost like a moving picture frame. Where New Way folds and contorts, Old Way is about elegance and exactness: every line crisp, both sides balanced.

olimpico

General

When a player scores straight from a corner without the ball touching anyone else.

oliver twist

General

Drunk. Rhymes with 'pissed', and yes, it's nicked straight off the Dickens novel — the rhyme worked, the name was famous, job done. Often clipped to 'Oliver' on its own once everyone around the table knows the code.

ollie

General

The foundational skateboarding trick in which the rider pops the tail of the board against the ground with the back foot while sliding the front foot forward, making the board leap into the air with no hands. It is the basis for the majority of modern street and vert tricks.

ollie north

General

A stylized ollie in which the front foot comes off the nose of the board in mid-air before returning to land; a one-footed ollie variation.

omae

Internet

A casual and sometimes rude Japanese word for 'you', recognised by fans from tense standoffs and the 'omae wa mou shindeiru' meme.

omae wa mou shindeiru

Internet

A dramatic catchphrase quoted endlessly by fans, usually set up to bait the reply 'NANI?!'

omake

Internet

An extra or bonus included with anime or manga — a short comedic strip after a chapter, a mini-episode, or a DVD extra. Literally a little 'something more'.

omegalul

Gaming

An enlarged, distorted version of the LUL emote (a laughing John 'TotalBiscuit' Bain), used for maximum-tier laughter.

omerta

Street

Omertà is the code of silence forbidding cooperation with authorities. Breaking it, by informing, is punishable by death within the organization.

omg

Internet

Stands for "oh my God" (or "gosh"), used to convey surprise, excitement, or dismay.

omi

General

In Polari, a man. It derives from Italian 'uomo' (man) by way of Parlyaree, the lingo of travelling showpeople.

omi-palone

General

In Polari, a gay man, formed by joining 'omi' (man) and 'palone' (woman). It let speakers name themselves and each other safely when homosexuality was illegal in Britain.

omnichannel

General

An approach that integrates every sales and communication channel into one seamless experience.

omnicrafter

Gaming

Someone who's leveled all eight crafting classes to the cap. High-end recipes need multiple crafts feeding into each other, so going omni is basically the goal if you take crafting seriously.

omo

Internet

An exclamation of surprise or shock, comparable to 'oh my gosh.' Often doubled as 'omo omo.'

omo iya mi

Street

Literally 'my mother's child'; used between close male friends whose bond has grown well beyond ordinary friendship into something family-like.

omoge

Street

Literally 'child of beauty'; a term of admiration for an attractive, well put-together young woman.

omw

Internet

A notorious white lie sent before you've actually moved a muscle, buying time while you finish getting ready.

on a bag

Street

Describing a determined, money-driven mentality in someone.

on a g ting

General

Seriousness oath. Same energy as 'on my mum' or 'no cap' — a verbal stamp that what you're saying is real. 'G' here means gangster / proper one, so you're vouching on that identity.

on a thing

Internet

Being romantically involved with someone in an ambiguous middle zone, not quite fully casual but not formally a relationship either. A cousin of the situationship.

on basic

Street

Being on the 'Basic' level of the Incentives and Earned Privileges scheme, with minimal privileges, usually as a punishment.

on bro

Street

Used to emphasize sincerity at the end of a statement.

on da wes' bank

Street

Refers to everything across the Mississippi from the main bulk of New Orleans — Algiers, Gretna, Marrero, Harvey, Belle Chasse, the whole strip. Confusing on a map, because the river bends so hard around the city that 'the West Bank' is actually due south or even east of downtown at points. The yat-flavoured pronunciation 'on da Wes' Bank' (dropped R, swallowed T) is the giveaway you're talking to a local.

on dead dawgs

General

Boston's heaviest swear-to-it. Sits in the same slot as 'on God' or 'on my mama,' but you're swearing on the friends you've lost — which is why it carries more weight than a casual 'deadass.' Charlestown and Dorchester teenagers built the phrase; it spread through Boston drill and TikTok. Often abbreviated 'on DD.'

on deck

General

Borrowed from baseball — the order coming up right after the one currently firing. Lets the line pre-grab proteins, drop pasta, start the sauce so there's no gap between tickets.

on fire

General

Performing exceptionally, especially shooting, as though unable to miss.

on fleek

Internet

Now somewhat dated and often used nostalgically or ironically.

on foe

Street

A phrase used to swear you're telling the truth, short for "on foe nem" (on my folks/friends/the gang). Saying "on foe" is like swearing on your loved ones that something is real.

on jah

Street

A vow of truth where 'Jah' is the Rastafarian name for God. Saying 'on jah' is swearing on God that you mean it.

on me

Street

A swear, with the speaker as the collateral. Saying 'on me' is staking your own name on whatever just came out your mouth — short of swearing on your mama, it's the strongest 'I'm not lying' you can drop without naming anybody else. Heavy in DFW street talk and Texas rap.

on me bill

General

On your own, alone. Liverpool rhyming-style shorthand — often said when someone's been left to it or chose to do something solo. Works neutral or slightly sad depending on the delivery.

on my radar

General

An item you're conscious of and monitoring, even if not acting on yet.

on one

General

Behaving recklessly, kicking off, in a foul mood and taking it out on everyone. The vibe is unpredictable — give them space.

on paper

Street

Being subject to conditions of parole or probation after release, when a violation can send you back.
