Get the Grommet mug.
The area by the penis/vagina where huge amounts of hair grow and evolve while being unshaved. This is usually the result of a dirty, homely being. It would be similar of grabbing and running your hand through a brillo pad or a black mans nappy hair.

Enthusiastic snowboarder.

From the claymation movie "Wallace and Gromit - A Grand Day Out" in which Gromit does a little snowboarding on the Moon, which is made of cheese.

An Ass Grommet is a rubber sex-toy from MEO available in several sizes that keeps a guy's asshole wide open -- his anal opening is stretched more or less permanenty so his butt-fuckers can get their big dicks into his ass easily. May be worn 24/7 so a dude gets his boy-hole opened wide for easy access. No more saying "Stop! It's too big!" when some hottie wants to poke a hole with his cum-cannon.
Matt bought me an Ass Grommet so I'll be able to enjoy his and other cadets crotch-rockets!
