Similar to a donkey punch only when you're having sex with someone from behind instead of punching them in the back of the head you use both hands and punch them on each side of the head simultaneously in a Donkey Kong fashion. Warning this will sometimes cause them to lose consciousness and lose control of their bowels, however it always results in a very tight clench of their muscles resulting in an amazing orgasm for yourself

When a male shaves his pubies before getting his peepee sucked by a girl. as the male "ejaculates" on the female's face, he throws his shaved pubies at her face making her look like a gorilla, hence the name "gorilla punch".

This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
