"B" Terms

broligarchy
General
A group of local 'bros' who dominate and gatekeep a surfing spot, enforcing who gets waves.
brolly
General
RAF aircrew slang for a parachute — because when it opens above you it looks like an umbrella, and 'brolly' is the British nickname for an umbrella. WWII vintage and still in use. Hitting the silk, taking to the brolly, same thing.
bronca
General
A problem, difficulty, or quarrel; 'no hay bronca' means 'no problem'.
bronx cheer
General
A loud, sarcastic jeer from the crowd, often a raspberry sound, expressing disapproval.
brony
Internet
An adult fan — historically male, though the label has broadened — of My Little Pony: Friendship Is Magic and its spinoffs. Defined as much by the community (conventions, fan art, OCs, podcasts) as by the show itself. Female-identifying fans often use 'pegasister' instead.
bronze up
General
Coating yourself head-to-toe in your own shit — usually in segregation — to make guards refuse to touch you during a cell extraction, search or transfer. A protest tactic of last resort, particularly associated with long-term solitary in the UK and Australian systems.

Geordie for Newcastle Brown Ale, the strong brown beer brewed on Tyneside since 1927. Comes in the iconic clear bottle with the blue star. Also called the Dog (as in I'm off to walk the dog — i.e. the pub).
broon ale
General
Newcastle Brown Ale, the region's iconic bottled beer, nicknamed 'the Dog'.

brown beat

The drum break from Cameron Paul's 1987 'Brown Beats' breakbeat record, the other DNA strand of New Orleans bounce alongside the Triggerman. Producers and DJs layer it under chants and call-and-response to keep the second-line bounce in the pocket.
brown bread
General
Figuratively, finished, done for, beyond saving.
brown shoe
General
A naval aviator or aircrew member, as opposed to a 'black shoe' — the surface warfare officer or sailor working the ship itself. Two tribes in the Navy with the eternal rivalry to match: who really runs the carrier.

General
A feral or wild horse, especially in the Australian outback.

Trader gospel: when the price drops, don't panic — buy more. Originated in equities, adopted with religious fervour by crypto Twitter, where it gets shouted on every red day. Works brilliantly in bull markets and catastrophically in bear markets, where every dip just dips harder.

Internet
Stands for "by the way," used to add a side note or change the subject casually.
btw i use arch

A submariner. Used by the rest of the Navy for anyone who serves on submarines — half affectionate, half ribbing. Bubbleheads wear it themselves with pride; surface-fleet sailors (skimmers) use it as a jab.
bubbler

A public drinking water fountain. The term is dominant in eastern Massachusetts and eastern Wisconsin — two pockets that, weirdly, share the word while the rest of the country says 'water fountain' or 'drinking fountain'. Often pronounced 'bubblah' in Boston.
buck
Street
To get violently energetic, rowdy, mosh-pit-aggressive. Central to Memphis crunk and Three 6 Mafia's whole live-show energy — see 'Get Buck Muthafucka'. Different vibe from 'getting buck wild' elsewhere; in Memphis it's a specific kinetic command.
buck fifty
General
A signature prison wound: a razor blade dragged across the cheek from ear to mouth, leaving a permanent scar that takes — legend has it — about 150 stitches to close. Hence 'buck fifty', street slang for $1.50. Often given as a mark of disrespect so the victim wears the verdict for the rest of their life.
buck rogers time
General
When the year you're eligible for parole is so far in the future it feels like a sci-fi setting. Named for the pulp-era space hero who woke up in the 25th century. Used grimly — if you're doing Buck Rogers time, nobody's joking.

A term for made baskets, or points in general; calling someone 'buckets' means they score at will.
buckeye

A native of Ohio (the Buckeye State), also a peanut-butter ball dipped in chocolate to resemble the buckeye nut.
buckhead
Street
The upscale district on Atlanta's north side. Lenox Square, Phipps Plaza, Tongue & Groove, the gated streets where the labels live. When a rapper says Buckhead, they're flexing the postcode.
buckley's chance

Almost no chance at all; often just 'Buckley's'.
bucks
Internet
The most common informal word for dollars.
