A sexual carnival of sorts in which a gentleman performs oral sex on no fewer than 3 different ladies in the same room no more than a minute apart. Used especially in reference to particularly sloppy oral sex, as an actual pie eating contest generally results in a messy face.
May also refer to a situation in which several men perform oral sex on several women, with or without switching partners.

A two-man variation on 'teabagging' in which the four testicles represent the swinging balls of a Newton's Cradle. The slapping of the two scrotal sacs together in an approximation of the cradle motion is optional, if physically achievable.
Joe was so wasted, we took about 30 pictures of him getting a Newton's Cradle while he was passed out.
