fat blocker

this is the term commonly used for the guy who is willing to "take one for the team" and hook up with the fat ugly friend that is usually blocking a much hotter and skinnier woman.

fat blockers are usually very non-discriminate and have a lower than average tolerance for alcohol, thus making the fatter ladies appear more attractive.

Every man should have a fat blocking friend.

guy 1: "I need a fat blocker before I make my move. Where did Brian go? He's the best fat blocker in town."
