A deviant sexual act whereby a large log-like turd is frozen in a freezer and once solid is then used as a dildo to fuck a girl's pussy. It can be done by a girl on her own, or as a group activity with two or more people. If others are present, the shit that is left behind inside her as it melts can be licked away.
Dude, did you hear what 'guy' did to 'girl'? He gave her a 7-inch Ice-burner last night! Those two are fucked up!
