undergash

A large, lumbering beast indigenous to the Midwestern United States. Enjoys preying on Jagermeister and cans of jalepeno cheese deep. Frequent visitor to an underground cult known as "Ars" - although no one ever knows he's there. Name not related to UK slang word for "vagina" - so don't even ask

Undergash - who's he again?
