The term "Butt Smegma" dates back a few hundred years. Butt Smegma is a cheesy-like curd that gathers between butt cheeks, where light cannot gather. It can be caused by hostile gases in a confined area, old lunch and moist hair. Even bad news has been found to cause Butt Smegma. This moist layer of tangible smell is salty to the taste and is not latex based. It cannot be washed off. It must be mechanically removed by a scraping action, such as the edge of a new credit card, driver's license or well cared-for front teeth.
Randy told Kelly that the spot at the lower rear of his trousers looked like (say it with me) "Butt Smegma".
