An extremely sarcastic comment stated by men who are trying to describe a girl that is one, or any combination of the following: fat, bitchy, moody, dumb, annoying, or abstinent . When stating that a girl has a "great personality" it is usually to give the illusion to any surrounding "great personalities" that the guy who is talking is actually not critisizing the blatantly negative aspects of a womans character, when in fact he rightfully is.
Dude1:"I cant belive this girl is freaking out over nothing! WTF?!?!?"
Dude2:"I told you man, shes got a great personality..."
