Schwidt
Schwidt: An extremely disgusting scat-based act of love involving having two men or women, or a man and a woman, or two transvestites, placing their anuses up against each other. One then defecates into the others anus. The person who receives the excrement then holds the excrement in their anus for a short period of time before defecating the excrement back out. The two partakers in the act then eat the excrement together.
Yo, my friend just showed me this video last night. It was disgusting. These two people had a schwidt together. That shit blew two girls one cup out of the water on the barf-o-meter!
