BRRAAPP! 

The sound made when a gay man pulls his dick out of his boyfriends cornhole, then proceeds to slap him in the face with it.

Damn did hear that BRRAAPP! when Lex slapped his shit cock on Dave’s face?

brraaap

Refers to the sound used in many drum&bass and even more dubstep tracks: a low sub-bass sound rattling your ribcage.
This sound is usually put under a beat.
There is a difference between a 'wobble' and a 'brraaap' but don't ask me what it is ;)

Also: An expression to state something is cool

Brraaap! What a bassline, dude!

Brraaapp

Brraaapp is a word everybody in St. Helen, Michigan should know. It is the sound of a machine (quad, side by side, etc.). Brraaapp is the perfect sound! I love saying it, too!

Friend: I did the jump and my quad was like, brraaapp!
You: OMG! What! I love listening to that sound!
