When a guy/girl masturbates while thinking naughty thoughts about thier friend. These are usually pornographic, and very graphic.
Girl 1: God... your such a Friend Bater... I know your thinking of him while your touchin' yourself.
Girl 2: Oh really... how?
Girl 1: Cause you moan his name, and I can hear the bed sqeaking.
