bizarre
General
Bizarre is the ballroom category where pretty is irrelevant and weird is the whole point. The brief: build a costume and silhouette so elaborate, so alien, so far from the human shape that the audience can't tell there's a person under there. Think otherworldly creatures, distorted proportions, avant-garde monsters. It's the scene's purest test of imagination and craft — strangeness is the currency, and the judges reward whoever travels furthest from looking like anybody.
bizzies

The police. Standard Scouse shorthand — older than half the force itself. Used the way Londoners say 'old bill' or Americans say 'cops'.
bka

Surgical removal of a lower limb at a level below the knee joint, preserving the knee.

Dota's Black King Bar. Pop it and you shrug off enemy magic and disables for the duration, so you can fight through a stunlock instead of dying in it. The classic carry survival button.
blaa

Deeply, painfully embarrassed. Not just blushing — full ground-swallow-me-up mortified. The 'black' is an intensifier, like 'utterly'. Classic Scots reaction to your weans showing you up in Tesco.
black and blue
General
A steak hit so hard and fast on the grill that the outside is properly charred — almost black — while the centre stays raw and barely warm: the blue. Requires a screaming-hot surface and a thick cut. Polarising order: chefs either respect the commitment or quietly think you're showing off.
black and white
General
Describing a Newcastle United supporter, after the club's black-and-white strip.
black cat
Internet
A person with an enigmatic, hard-to-read, self-sufficient personality in a relationship, often paired conceptually with a 'golden retriever' type. Alluring but low-key.
black cat girlfriend
Internet
A black cat girlfriend is an enigmatic, self-contained partner who is hard to read and comes and goes on her own terms, like a black cat.
black cat lesbian
General
The aloof, self-contained, slightly mysterious half of a couple. Femme, independent, a bit of a mean-girl edge, affectionate strictly on her own terms, like a cat that picks one person and ignores the rest. Pairs perfectly with a golden retriever lesbian who's delighted to chase.
black disciples
Street
Chicago street org formed when David Barksdale and Larry Hoover's coalition fractured — the BDs broke off from what became the Gangster Disciples in 1974. In the drill era they're the side Chief Keef, Lil Durk, King Von and the entire O'Block / 600 / GBE world rep. Symbol is the six-point star and the number 3 (trey). Half the names you see in drill lyrics — 300, 600, 051 — are BD sets.
