The bottom 25-50% of a girl's exposed butt cheeks when she wears tiny shorts. This skin is rife with bacteria from when she has sat on a toilet, thus, a breeding ground for spreading bacteria to every surface.

The state of your butt when you stand up from a public toilet, particularly when it has someone else's pee on it.

Your desperate attempt to wipe the foreign pee off your butt by rubbing it against the inside of your pants. Ewwww.
