The sexual act of having someone take your own feces and smear it across your upper lip after violating you with rigorous anal sex, causing you to walk like Charlie Chaplinthe next day. This will also result in a brown staining of the upper lip for the next 48 to 72 hours. The act is typically committed against other males while passed out drunk, and although common, not necessarily committed solely by fraternity brothers.

dress up like batman with a utility belt, a cattle prod, a spray can and a gun and run around at night and when you see someone shit on him or her then spray them with your spray can and start beating them senseless then zap them with your cattle prod and then murder them with your gun.
Batman: hey robin wanna do some late night muddy Texas winged prodding?
