A wadded up clump of toilet paper, ampened, then placed length wise in the crack of the anus. If done after a long day of salsa shits or diarrhea, the user simply sleeps with the paratrooper in place. The anus will feel painless and clean the next morning.
"Oh my god, my ass has been dripping all day long. I gotta remember to throw in a paratrooper later tonight."
