Big Fat Friend. The larger less good-looking friend of the hot girl at the bar. She can sometimes cock block a guy who is trying to sleep with the hot girl. Best to combat this by deploying your wing man.

Sheila was looking so hot, I was really trying to get up in that; but her BFF kept getting in the way.
