Public seats are dirty....just use your imagination. Once you sit your pants down on a public seat, you now have "public butt" because whatever disgusting stuff that was on the seat (from the thousands of other butts that have sat there) is now on your pants. For all you know, the guy that sat in that seat before you could of had some diarrhea that leaked through his pants and now its rubbing off on yours. Disgusting isn't it. One should think twice about tainting seats, beds, or couches in their house once they have "public butt."

The state of your butt when you stand up from a public toilet, particularly when it has someone else's pee on it. The overwhelming disgusted feeling that you suddenly have and the mental vows that you make to never make this mistake again. Your desperate attempt to wipe the foreign pee off your butt by rubbing it against the inside of your pants. Ewwww.
