Top definition
When a person gets on a toilet to defacate, only to be sat on top of by another person who defacates between his or her legs. There are three variations: standard, where both people face forward; the side-saddle, where the top person sits like a child on Santa Clause's lap; and the reverse, which allows the two people to make out with each other while defacating.

Brandon: "Jim, what the FUCK..."
