A fictitious town in South Carolina that represents the act of defecating. The town's name is rooted in the famed bowel movement term "Grumper." "I'm going to Grumpville" acts as a declaration that one will soon go to the bathroom to take a dump. Grumpville hosts a fictitious music festival called "Grumpfest." When attempting to go to Grumpville during Grumpfest there is obviously excessive traffic which allows the festival to act as jargon for constipation.
