Get the crusty mustymug. The art of placing turds on a mates forehead while they are stone cold drunk in the pattern of a crown. Upon waking, the hours have slightly dried out the turds to a crust that must be scrubbed off.
Gary passed out last weekend and we decided to make him a crusty crown so everyone at the party knew who the king was.
