Her: I'll be honest with you, I AM curious but not curious enough.
Him: Sounds like you are bum-curious to me.
Her: Well heres the deal, If yours goes anywhere near mine, My finger goes up yours
Him: Unless you are drunk, you mean?
Her: My bum is fair game if I'm drunk.

bum eating

Bum Eating is a form of Autocannibalism believed to have originated in the west african region.

The act of bum eating consists of one or more people using a razor blade to cut skin and fatty tissue from their bottoms. This “bottom steak” is then layed out flat and spices and a mashed up combination of nuts and berries are added and then cooked over a small electric grill. Outside of others helping a person reach the right area during a mutual bum eating session, bum eaters cut and eat their own flesh.

This is NOT a common practice and is looked down upon in the local society and is considered an insult to call another person a bum eater.

Stay away from the docks at night, that place is full of dirty sailors that are into bum eating.
