Used for elderly women generally, often as easy targets or unimpressed bystanders.
baby bear
General
A rookie police officer. Inexperienced, eager, and often the one writing tickets to hit a quota — so not as harmless as the name suggests.

A butch who's young, boyish, and often still inexperienced — early in the journey of growing into a masculine lesbian identity. Said with affection, sometimes a little teasing, by the butches and femmes who remember being there.
baby catcher
General
Affectionate hospital slang for an obstetrician. Strips the Latin off the job title and tells you exactly what they do: stand at the business end and catch. Also stretches to midwives and, in a pinch, the L&D nurse who ends up with the baby in her arms when the doc's hands are full.
baby stripper
General
Industry term for a stripper with under two years' floor experience — not an age comment. Baby strippers earn well on novelty but routinely lose money to bad shift picks, over-tipping out, and not knowing which custies are time-wasters. House moms usually adopt them.

The whole oppressive structure of Western society, government and finance that Rastas resist; title of a Bob Marley track.

baccy
General
Tobacco, especially loose rolling tobacco. Widely used across the UK but a particular fixture in Geordie and northern speech. Shortening of 'tobacco' with the affectionate '-y' tacked on, same way 'telly' came from television.
bach
General
An affectionate add-on tagged after someone's name or after 'love'. 'Come here, bach' or 'Dai bach' — it literally means 'little' but functions as pure warmth. The feminine form is 'fach', used after a woman's name.
bachelor's handbag

back burner

A person someone keeps as a low-priority potential romantic option, ready to pursue if their main interest falls through.

A grim euphemism for leaving prison only by dying, sometimes with burial on prison grounds.
back o' town
Street
The historic Black working-class district behind the French Quarter, stretching back toward the old New Basin Canal in what's now the Superdome and Central City area. A cradle of early jazz — Louis Armstrong was a Back o' Town kid. Largely erased by mid-20th-century 'urban renewal' that bulldozed the canal and built the Dome.
back of bourke

A very remote location; the far outback.
back of rackhams

General
A triumphant shout when the ball hits the net; the ball is typically trapped at the back of the net until retrieved.
back out

To draw a weapon — typically a knife or gun — from where it's stashed (back pocket, waistband, bag). Drill-pack staple verb, heard constantly in bar one whenever a violent scene is being narrated.
back rolls!?
General
The sound of an insult landing somewhere tender. You repeat the read back as a stunned question — '...back rolls?' — because you can't believe she went there and you're not over it. It's the perfect template for any too-personal jab: echo the exact words in pure disbelief. Alyssa's confessional delivery, all hurt eyes and slow blink, is the whole joke.
back teeth are floating
General
Another vivid way to say one urgently needs the bathroom.
back up the truck
General
To load up on a stock or bond in enormous quantity, the mental image being reversing a dump truck up to the loading dock and filling it. Used when a trader thinks an asset is so mispriced or such a screaming buy that small nibbles won't cut it.

Slip past the action, get into the enemy base alone and start hitting towers or the nexus/throne while the whole map is looking the other way. High risk, game-ending if it lands.
backdraft
General
A smoke explosion. A fire in a sealed space burns down its oxygen and stalls; pent-up unburned fuel gases sit there waiting. Crack a door or break a window and the rush of air re-ignites the lot at once, blowing fire and pressure back through the opening.
backheel

A pass or shot struck with the heel, usually to move the ball in the opposite direction to which the player is facing.
backie

A ride you get on the back of someone else's bike — perched on the rear pegs, the saddle, or just clinging on while your mate pedals. Classic schoolyard transport across Scotland and the north of England. Free taxi, slightly illegal energy.
backline

Your supports and ranged DPS positioned safely behind the frontline. They do the work from distance but fold the second someone gets in their face.
