Butt Rag (aka ass tampon). After
taking a dump and wiping clean, you tear off 2 to 3 squares of
toilet paper, fold them on top of each other to form a square, then fold that in half, then (optional) you apply some baby or talcum powder to the outer edge. Then wedge it between your
ass cheeks in the crack. Keeps your underwear nice and skid free until the next dump.
