Latest slang terms

orange hanky
General
In the gay leather hanky code, orange is the wildcard. It doesn't lock you into one kink — it broadcasts that you're open, adventurous, and down to negotiate just about anything. Worn back left pocket = you take the lead; back right = you receive. The code itself started in the 1970s so men could cruise each other in bars without saying a word out loud, back when saying it out loud was dangerous.
órale pues
General
A closing agreement, like 'alright then' or 'okay, sounds good'.
órale
Street
The Swiss-army knife of Chicano interjections. Means right on, alright, hey, c'mon, let's go, hell yeah — whatever the moment needs. Tone does the work.
or no?
General
A phrase placed at the end of a question or invitation to let the listener opt out gracefully.
opulence, you own everything
General
The signature call of ballroom emcee Junior LaBeija, immortalised in the 1990 documentary Paris Is Burning: 'O-P-U-L-E-N-C-E! Opulence. You own everything!' He spat it out while judging a queen, and it became one of the film's most quoted lines. It's a hype chant and a fantasy — the idea that on the ballroom floor you embody the wealth and ownership the world denied you offstage. Decades later it still echoes through drag and queer pop culture.
option select (os)
Gaming
A single sequence of inputs that the game resolves into the best outcome depending on the opponent's action. You don't have to react — the engine sorts it for you. Borderline cheating, totally legal.
option
Gaming
A little helper unit that orbits or follows your ship. Doubles your shots, and in some games physically blocks incoming fire.
optimize
General
To adjust something to achieve the best possible performance or result.
optics
General
The public or internal perception of a decision or event, independent of its substance.
opt-in role
Internet
Any role members can pick up on their own — usually via reaction roles, a slash command, or a server's onboarding menu. Contrast with staff-granted roles like Mod or Verified. Used for ping groups, interest tags, and access to optional channels.
opsec
General
'Operations Security' — the practice of identifying and protecting critical information so adversaries cannot piece together friendly intentions, capabilities, or activities.
opps
Street
Broadened in mainstream use to mean anyone you're against, even casually — a sports rival, a hater, or someone you just don't mess with.
opposite
General
Describes performing a spin, grind, or trick in the direction opposite to the rider's normal, comfortable one. Doing tricks opposite is a mark of well-rounded skill.
oppo
General
Your opposite number — the bloke who covers your role on the other watch, shift, or crew. By natural extension your closest working mate, the one you trust to hand over to.
oppalogist
Internet
A (usually female) fan who makes excuses for her male bias no matter what he does; a blend of 'oppa' and 'apologist'.
oppa
Pop
A Korean term a girl or woman uses to address an older male — literally 'older brother,' but also for older male friends, partners, or idols.
opp block
Street
Used loosely in rap and online for any rival's home territory you wouldn't want to be seen on.
opp
Internet
An enemy or rival — originally a rival gang member in drill lyrics, now diluted to mean basically anyone you're up against. Common in rap, gaming, sports trash talk and friend-group banter.
opord
General
'Operations Order' — a directive issued to subordinate units to carry out an operation, traditionally in a standardized five-paragraph format (Situation, Mission, Execution, Sustainment, Command and Signal).
open the kimono
General
To share internal or confidential information openly with another party. Now widely avoided as dated and culturally insensitive.
open outcry
General
The old-school way exchanges matched orders: traders in coloured jackets stood in a pit and screamed bids and offers at each other, backed up by hand signals so the noise didn't matter. Mostly extinct now — screens ate the floor — but the CME held on to a few pits well into the 2010s.
open edition
Internet
A mint where an unlimited number can be minted within a set window (or other variable), so supply is determined by demand and time rather than a fixed cap.
ope
General
The involuntary syllable that flies out of a Midwesterner's mouth the second they almost bump into you, reach across you for the ranch, or squeeze past you in the cereal aisle. Half apology, half throat-clear. Functions as a verbal turn-signal — you don't decide to say it, it just happens.
op shop
General
An opportunity shop selling second-hand goods for charity; 'op shopping' is thrifting.
