Similar to the visual of a "spider swing" (which is executed when two individuals sit facing each other on a swing so that their legs cross), spider pee occurs when a girl sits on a toilet, spreads her legs, and a pees, while a guy pees downward between her legs into the same toilet. The legs recreate those of a spider's on either side of the body, and it represents a form of ultimate love between two individuals. But spider poo crosses the line so don't do that you nasty ho.
