Occurs when one frat boy straddles the neck of another and simultaneously urinates in the bottoms mouth while defecating on his chest. Typically this is reversed after the top is done. Often, some of the other frat guys watch and wait to get in on the action.

This is a very common act among fraternity boys, who often find themselves missing each other during periods of the day. Many times they will skip classes or walk quickly away from girls to engage in the frat boy teeter totter.
