A double wammy is when a dude is fucking two girls at the same time and puts on a strap on his but and fucks both girls at the same time.
Yo I gave those two girls at the club a double wammy. I was fucking two girls at the same time and puts on a strap on my but and fucked both girls at the same time.
It’s the act in which you sit on someone’s face and shove their nose up either your ass or your vagina. This usually ends in your partners nose being broke.
