An infestation of dingleberries in one's anus, generally caused by an overly sweaty ass crack, or from taking a shit right after a shower while ones ass is still wet. The toilet paper disintegrates into many pieces, becoming entangled in ass hairs, resulting in a Dingleberry Fiesta. Most often caused by super soft or thin toilet paper.
When a fourth generation dingleberry matures to the size of a walnut and other hairs are conjoined into the over-sized dingleberry forming a gate of excruciating pain. As the dingleberry expands and pulls the hair, the O-ring swells up like a female baboon.
