When an incision is made to the scrotum and a penis or penis-like object is used to have intercourse with the open scrotum; a technique usually favored by masochists to increase pain and heighten arousal.
I gave Jimmy a Penguin Express because he is a homosexual masochist and I am a sick, sadistic freak.
