flap 

To masturbate with foreskin, similar to fap, but specifically for an uncircumsized penis.

I'm not circumsized, so I flap instead of fapping.

plain and simple: a fart. ur asscheeks flap together

also known to happen during explosive diarrhea thus making the sounds and creating discomfort. the force of the flap may cause u to utter many high pitched jitters while exploding (just like in the movie dumb and dumber)
