backdoor freezer burn

Backdoor freezer burn is when a guy is fucking a girl from behind and has a jar of Icy Hot within reach. He heavily coats his finger with Icy Hot and shoves it in the girl's asshole, resulting in an intense sensation of cold in her rectum, followed by an intense burning sensation, as well.

Hey, why was Sahil crying when he left the party?

Yeah, about that, Ben actually gave him a backdoor freezer burn.

Oh, shit.
