"B" Terms

boost
Gaming
Crouch under a teammate and they can stand on your head, gaining height for an angle or a peek nobody expects. A boost opens off-angles, lets an AWP see over cover, or sneaks a player onto a perch the enemy never checks.
boosted
Gaming
Describes a player sitting at a rank above their real skill, usually because someone better dragged them there, duo-queued them up, or straight-up played on their account. A favourite insult for anyone playing badly at a high rank.
booster
Street
A booster is a shoplifter, one who steals merchandise from stores, often concealing it in special clothing or 'booster bags.'
boot
General
US Marine Corps and Navy term for someone who's just graduated boot camp. The shine isn't off them yet — fresh haircut, fresh uniform, no experience, no stories. Used by everyone senior, which in the fleet means everyone. By extension, anyone new to a unit, posting or job is 'a boot' until they've earned otherwise.
bootcamp
Gaming
An intense in-person practice block where a pro team trains together in one place for days or weeks ahead of an event. Scrims all day, reviews all night.
bootleg
General
An offensive play in which the quarterback fakes a handoff, hides the ball on his hip, and rolls out in the opposite direction to run or pass.
bootneck
General
A Royal Marine. Worn with full pride by the Marines themselves and used by the rest of the British forces — particularly the Navy they serve alongside — with the usual mix of respect and ribbing. If you call a Royal Marine a bootneck you'd better mean it the right way.
boots
General
A ballroom-and-drag intensifier that turbocharges whatever comes before it. Tack 'boots' onto an adjective and you mean it to the maximum — 'sickening boots' is sickening at the highest possible level. Lives in the same family as 'the house down.'
bootsy
Street
Oakland-flavoured way to call something corny, weak, or beneath the standard. If a move's bootsy, it's the kind of thing nobody respectable would pull.
booty-do
Street
A body shape where the gut juts out past the backside. The whole joke lives in the sentence: your belly do more than your booty do.
bootylicious

A general term for fabulous or impressively good, extended beyond bodies.
booyah

A public house; or, of a person, someone who drinks heavily.

bop

bora
Street
A knife — usually a long one. Drill shorthand that started in UK road slang and got swallowed whole by NYC drill once Brooklyn started rhyming over UK beats.
boracic
General
Completely broke or out of money. 'Boracic lint' rhymes with 'skint', and it's clipped to 'boracic'.
boracic lint
General
Cockney rhyming slang for 'skint', meaning flat broke, no money. Almost always shortened to 'brassic' in modern use (so much so that most people who say brassic have no idea it started as boracic lint, a medicated dressing).
bore da
General
The everyday Welsh greeting for the morning, widely heard even among non-Welsh-speakers.
boreen
General
A small country road — barely wide enough for one car, hedges scraping both wing mirrors, grass growing up the middle. The classic Irish backroad. From the Irish 'bóithrín,' literally 'little road.'

bossman

What you call the man behind the counter — chicken shop, off-licence, corner shop, barbers. A respectful catch-all when you don't know his name. Doesn't imply he actually owns the place.
bosso
General
Spanglish loanword for one's boss or supervisor.
bostin
General
Excellent, brilliant, smashing. The classic Black Country and Birmingham seal of approval. From the verb 'bost' meaning to break or burst — so something 'bostin' is so good it's bursting.
boston cooler
General
A blended float made from Vernors ginger ale and vanilla ice cream. Named for a Detroit street, not the city of Boston.
boston marriage
General
A 19th- and early-20th-century term for two unmarried women sharing a home and a life, financially independent of any man. Some were romantic, some weren't — the phrase let polite society leave that unspoken. It got its name from Henry James's 1886 novel The Bostonians, which centers on exactly this kind of arrangement, though James never used the words himself. His own sister Alice lived one. Common among suffragists and the early college-educated set.

bottom
General
The Bottom is on the receiving end — taking the sensation, the restraint, the impact the Top delivers. Like Top, it's a physical role rather than a psychological one. Bottoming isn't the same as being submissive; a Bottom can be calling every shot while taking the action. Plenty of power lives at the bottom.
bottom turn
General
The first turn made at the bottom of a wave after the drop, redirecting the surfer back up the face and setting up everything that follows.
bought the farm
General
To be killed. Originally aviation slang for a fatal crash, the 'farm' being the cemetery plot; extended to any killed-in-action service member.
boujee
Aave
Acting or living in a fancy, upscale way — sometimes admiringly, sometimes as gentle mockery of pretension.
