Gimp

A female who overvalues a man who wouldn't do the same back. Mainly girls who fall for guys that will only hurt and cheat on them but continues to chase after them any chance they get.

Girl 1: "Is she really dating that guy again? He's cheated on her three times already!"
Girl 2: "Yeah, she always falls for his sappy excuses and refuses to ever leave him. She's such a gimp."
