A man with a propensity for engaging in anal sex with women of grand proportions.
Eddie got so trashed on Friday that he went all chunk spelunker on that 900lb slab of white beef. When he regained conciousness the next morning, he had to pull on the rope to find his way out. He hasn't been the same since.
