Friends with Friends

So meeting new people in college is sweet but have you come across a friend who has a group of friends from their school or their dorm and they are complete asswholes. Well I have. It sucks cause its like “hey we should hang out” and at the same time your like “hey dont bring that douche-bag of a friend of yours along with you” This seems like its more common in groups of girls where one is wicked cool and then one in her group of friends is a complete bitch to you for a reason you dont even know. I dont know if anyone else has come across this problem but it kinda sucks.
