"B" Terms

bobol
General
Illegal or corrupt activity, especially embezzlement or graft in business or politics. Also bobbol.
bobolee
General
A person who is repeatedly blamed or abused; from the Judas effigy beaten on Good Friday.
bobos
Street
The generic, no-brand shoes handed out to inmates, often mocked as low quality.
bobowler
General
A big moth. Specifically the dinner-plate hairy ones that bomb your living room the second you open a window in July. Beloved Brummie word, often weaponised to scare younger siblings.
bobtail
General
A tractor unit rolling without a trailer hooked up. Looks stubby and weird without the box behind it, hence the name — like a dog with a docked tail. Can be a noun (the truck itself) or a verb (the act of driving one that way). Bobtailing is sketchy in the wet: no trailer weight on the drives means the back end wants to swing out under braking.
bochinche
General
In Puerto Rico 'bochinche' means gossip or juicy talk (elsewhere it can mean an uproar).
bockety
General
Physically unsteady, wobbly, lame or falling apart; used of furniture, structures or a shaky gait.

A cultural touchstone of NYC, particularly in Latino neighborhoods.
bodega cat
General
A cat kept in a bodega, ostensibly for pest control but beloved as a neighborhood mascot judging your late-night snack runs.

To completely demolish someone in a competition, argument, or rap battle; to be 'bodied' is to be thoroughly beaten.
body
General
In ballroom, Body is the category where the only thing being judged is your physique. No costume to hide behind, no story to spin — you walk to be read on shape, proportion and how you carry the flesh. It splits into sub-categories so nobody's compared unfairly: Model-Thin (lean, runway frame), Muscular (built, gym-cut), Luscious (soft, full, sensual), and Big Girl / Big Boy (the bigger queens and kings serving confidence). You don't win Body by being one ideal — you win by owning whichever one is called.
body block
Gaming
Standing in the way on purpose. You eat a skillshot meant for your carry, or wall off a chokepoint with your hitbox so the enemy can't path through. Tanks and supports live for this.
body check
Gaming
A mechanic that checks every player is alive and standing where they should be. One dead or misplaced body and the whole group wipes. No carrying dead weight through it.

The proportion of your bodyweight made up of fat versus fat-free (lean) mass; the real measure bodybuilders track rather than scale weight alone.

General
A patient who has ingested condom- or wrap-encased drugs to smuggle them, at risk of catastrophic overdose if a packet ruptures.
body roll
Internet
A dance move in which a performer rolls their body in a fluid wave, often used for sexier choreography. A recurring highlight in performances.
boeuf gras

A fart. Used as a noun for the trump itself, and as a verb for letting one go. Schoolyard staple across the North West.
boffin
General
British forces nickname for the back-room scientists and engineers — the radar people, the codebreakers, the weapons designers. Coined during WWII with affectionate respect: the boffins were eccentric civilians in tweed who kept inventing things that won the war. Still used in the UK for any clever-clogs technical type.
bogan
General
A person regarded as unrefined or lower-class, often stereotyped by dress, speech and taste. Can be affectionate or derogatory.
bogart
Street
To hold onto a shared joint or bowl too long without passing it along, monopolizing the smoke.
bogey
General
A radar contact you haven't identified yet. Could be friendly, could be a bandit, could be an airliner that wandered off course. The point of the word is that you don't know yet — once you do, it gets promoted to bandit or downgraded to friendly. WWII RAF slang that's now standard NATO brevity.
bogey dope
General
A brevity code requesting information on an indicated or closest group in bearing, range, altitude, and aspect (BRAA) format from a controller.
bogged
General
Of a vehicle, stuck fast in mud or deep sand.

boi
General
A boyish lesbian — younger, softer-edged masculine than 'butch', more skater-and-snapback than old-school stone. Chiefly a UK read. The respelling does the work: 'boi' signals it's a queer identity, not just a haircut.
boil the jug
General
To switch on the electric kettle to make a hot drink. In New Zealand a kettle is commonly called a 'jug'.
boil the ocean
General
To attempt something impossibly large or to overcomplicate a task by trying to analyse or do everything at once. Used as a warning against scope creep.
boiler

In underworld slang a 'boiler' is a stolen car, an innocuous-sounding cover word.
boiler room
General
A sales operation, usually a cramped room of cold-callers working off scripts, that uses aggressive pitches to offload thinly-traded or worthless securities on unsophisticated investors. The house owns the stock, the brokers pump it, and when retail is loaded up, the insiders dump. Made famous on screen by Boiler Room (2000) and The Wolf of Wall Street.
boke

Nausea or the urge to be sick ('gie me the boke').

bomb diggity
Pop
Excellent or top-tier in a playful, exaggerated way.
bombardiro crocodilo
Internet

bombing

Your panic button and your safety net. A bomb clears bullets, deals big damage, and usually gives you a moment of invincibility. Smart players bomb early to kill a dangerous pattern before it fully expands, rather than waiting until they're already trapped.
bombshell
Pop
An aesthetic of full-glam, va-va-voom beauty — big hair, bold lip, hourglass styling.
