To grab somebody, usually a person of the opposite sex, by the back of the head
and press their face such that their nose
sealed against your asshole. You then
break wind, making a "snare drum" sensation that is pleasant
for both parties.
Guy 1: Why does
Cindy's have shit in her nostrils?
Guy 2: You didn't hear? We were pounding
that loud-ass snare
drum all night long.
Guy 1: Sweet-ass dude. I'm happy for both of you.
