Formal is tonight and I want to make a good impression on my boyfriends brothers.
 

The party will be at their house. I know some of the brothers because we are in the same classes and have hung out before, but I don't really know most of them. I just want to make a good impression. I know this is a pretty general question but any advice is appreciated. Thanks a bunch!!

Don't puke

^^^ ditto to what he said.

Don't be an obnoxious drunk.

Take the time to talk to them / get to know them - esp the ones that you haven't met before.

Smile and have a good time. Try to talk to them but don't force it. Being yourself will make a better impression than trying too hard to impress them.

Dont tell the DJ what to play, it's annoying.

Bring three 8 balls and a couple handles of brown liquor. It'll be great fun.

Are you really a "greek in training?"

That could be an interesting conversation piece. :)

I think she is probably interested in joining a sorority and she doesn't want to do anything stupid. Good idea.

Don't show them your tits. Well, maybe you should?!

Don't be that person who screams when they hear their favorite song. It's annoying.

Wow the formal was sooo much fun!!! Thanks to everyone for all of the great advice.
