Brapps

Believed to be a sign of admiration or love of a thing, Brapps is shouted by the user, and is often accompanied with the oft-used gangsta gun hand manouvre (making the gun signal with your hand and waving it). Brapps is used often to describe something which is good.

Origins
This one is easy. Place: Peckham. Date: About 10 years ago. First Use: Some guy.
