dirty ice cube 

An illicit sex act in which one party inserts a cube of ice into the anus of the other party. The ice is then thrust further inward with the first party's penis. Local legend suggests this practice originated with the Native Americans.

"Did you hear Lisa broke up with Tom? Yeah, he gave her the ol' dirty ice cube and she hasn't spoken to him since."
