Leg fap

A way prepubescent 12 year olds like to represent the act of fapping by slapping their hands against their legs, making a sound similar to fapping.

Man, did you see those pics of the Kardashians? *Leg faps*
(Friend shakes head repeatedly, because he knows his friend didn't actually see any pics)
