Similar to Trench feet, Trench Ass is a medical condition that is brought about by an excessive and long-term build up of moisture or faecal matter between a person's ass cheeks. Usually as a result of improper hygiene.

Common symptoms include: foul smelling cheeks, Bum Cheese, a lot of ass sweat or other liquids that may seep through clothing and onto chairs
