Why is that? I have a theory that it's so the other girl can look better in comparison next to the ugly chick, what say you?
Most Helpful Girl
I don't think it's a conscious things that girls do! Girls are friends with other girls because they enjoy each others' company. There may be some shallow people who think it boosts their chances having an ugly friend to be compared to, but most will be just as eager for their friend to hook up with someone nice as for they themselves to. I would much rather have a friend with me who could hold an interesting and funny conversation with any guys we met, and would make us seem interesting and fun to be with, whether she is better or worse looking than me - whatever! Girls just wanna have fun!1
