b-boy
n. (bee-boi)

In contrast to popular belief, the TRUE definition of a b-boy is not simply just a male breakdancer. The main difference between a breakdancer and a b-boy is that a breakdancer is one who uses the hip-hop art form known as breakdancing to get chicks and/or to show off to his friends that do not know shit about breakdancing or perhaps anything about hip-hop in general; in contrast, a b-boy is one who expresses himself through breakbeats (beats that b-boys can break to) using various combinations or sets of breakdance moves such as:
-toprock
-uprock
-downrock (e.g. 6 step)
-freezes (e.g. single hand baby-freeze)
-power (e.g. flares)
-airtracks (e.g. UFO)

A true b-boy will add his own style to these various sets. These sets are innovated by b-boys through rigorous dedication and practice during "session" or breakdance practice. Any set that is “taken” or “copied” from one b-boy by watching another b-boy/b-girl is called a “biter”.

A real b-boy will break anytime, anywhere, and any day, when challenged or "called out" by another dancer or b-boy/b-girl in a "battle". In many cases, a b-boy will encounter a dancer or another "b-boy/b-girl" that is "straight up whack" or simply disrespectful, in which case a b-boy will wish to "serve his/her ass". But in many cases, a battle between a b-boy and another dancer or b-boy/b-girl, will have both sides showin' much peace, love, respect and even props.

Simply put, a b-boy is one who encompasses the...

To eliminate a hard-on (go limp) by peeing instead of ejaculation. This is disappointing to men, so they don't want to go to the bathroom and piss off their hard-on. Then then say they are pissed off, or angry about it.

It has become slang for making someone angry or when something or someone makes a person angry.

Today, women have picked up on this term also, using it as getting angry (but not about their hard-on going away).

This is distinct from the imperative "Fuck off!" You try to say it as one word with the emphasis on the "fuck". This word has a couple of uses in Australia:

1. To qualify an adjective, if something is REALLY big or REALLY brightly coloured, for example, then you slide "fuck-off" in somewhere. This is also used in the UK and is seen in the movie Lock Stock and Two Smoking Barrels: "Also, I think knives are a good idea. Big, fuck-off shiny ones."

2. Another term for insect repellent.

To nob and off is saying to sum 1 they aint got no balls.

The act you perform when you blow off your homies for a hot ass chick when deep down your homies are being jealous of you cause you're kickin it with the girl they want which in conclusion. Its a justifiable blow off
