After a long night of drinking, when you fart and liquid shit, "like it was stragith water i was shitting beer down my leg", balled up toilet paper in your ass crack to prevent leakage.
While at the mall, Greg was going upthe escalator and had his legs on two different steps, he sharted in his pants and he needed an ass tampon for the leakage.
When a gay guy gets banged too often up the ass, and one day it just doesn't close up afterwards. So, the guy has to wear a tampon up his ass so all the crap doesn't fall out all over the place.
