Filling one's anus with ketchup and mustard and then pooping it out on a partner's face, in their mouth, and all over their body. The anal secretions are then licked up by other members involved in this sick disgusting orgy and swapped between each others mouth.
I walked in on my partners and their friends having a Gleason party! How disgusting!

The coolest last name ever! Most of the family is hilarious and it is a trait to be comical, (proof is the comedian Jackie Gleason). The family is pretty cool and has a constant occurance of twins. The men in the family all have large penises and are athletic competitors.
Man that family the Gleason's are always kidding, but they're good at sports.
