Funbo
The art of drawing upon a friend, with a permanent marker, who has passed out from excess alcohol consumption. Rude words and male genitalia pointing towards the mouth are frequently used.

Funbo is derived from an incomplete spelling of the word Funboy upon the forehead.

The only rule is that you may not funbo someone you currently live with. All outsiders are fair game.
We had to funbo whoever passed out first.
