4. Don't be an asshole
There is nothing more annoying than being with a friend who is bitching about the party the whole time. No one is asking you to come, so stop complaining that it's crowded, smells bad and that you aren't getting any attention. Yeah, maybe you aren't the hot biotch you thought you were, so get a personality and a smile on your face and have fun.
