The act of defecating on a girl's back, drawing a map of the world with said feces, and using your ejaculate as the polar ice caps. Only to be done on the dirtiest of whores. Not suggested on a loved one (unless they're into that).
Dude, I met this girl at the bar who turned out to be a gutter rat and told me to give her a Steamy Cartesian!
