When you are drinking a drink with ice in it, and you tilt the cup too far and the ice hits you in the face.
I was talking to Heather at Sean’s party last night, and I was about to ask her out but then I got ice slapped.
Freezing ones balls and then fucking a girl doggy style in the ass so the now hard and cold balls slap against her pussy making it tighter for when you enter her
P1: man I was ice slapping her so hard last night, my balls were numb!
P2: i bet she was tight as fuck.
