The Marcellus Erectus is a sexual act, where the male is going to pound town doggy style and screams "Do a kickflip" as he reaches climax, flips the female over onto her back, slaps her in the face with a bratwurst, then immediately grabs her ankles to roll her off the bed in a reverse somersault into nearby furniture.
