Never, ever, I mean EVER trust what one girl says about another, especially in these situations. If she is said to be cute, nice, or anything complementary, run for the hills man. Women won't talk nicely about someone hotter than they are, so if she's talking the other chick up, you know the other girl is uglier than she is. If a girl says someone she knows is a total squeak, go for it haha, I guarantee she's hotter than the girl talking smack.
oh, and LOL.
