* Refers to a game played between friends where points are earned for succefully having sexual intercourse with extremely obese women without being caught by one's friends. If a participant is caught during this horrific act points are taken away and added to the finders point total. These women only qualify if their obesity is comperable to the fat women featured in Spencer's gag cards.

* The Chamillionaire song "Ridin'" was created to commemorate a specific instance where the artist won this game by sexually pleasuring a morbidly rotund transvestite. This event led to additional (bonus) points for Chamillionare which gave him a solid lead and eventuallty a win in a game between him and his friends.
My friends caught me riding dirty. Now I need too sleep with six fat bitches in order to win.
