The act of not wiping your ass after taking a shit either because there is no toilet paperleft, or you just chose not to wipe. Leaving your butthole "poopy".
Guy: Shit. Some asshole didn't replace the TProle, guess I'll just have to have a Poopy Butthole
the most powerfull word ever known more powerfull then all the curse words all together. Able to make people turn into a poop head. Thats if it doesn't kill the guy u say it to.
