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.

When one person sits on top of another, chest to chest and interlocking legs, while on the toilet. The top individual pees through the bottoms legs. Similar to the past time of spidering on the swings at a playground.
