BRAP is basically like Jamming but with Synthesizers instead of Guitars, etc.
BRAP is also the name of Skinny Puppy's Back & Forth 3/4.
"Brap on!" (Skinny Puppy fan's "goodbye")
(More c0re version of the above)
"I went to the CD store and bought BRAP!"
As well as this, it was used by bikers in the 80's as reference to the sound of their engines.
Now most notably used in the UK by chavs who get to excited by anything and everything.
