Basically some "friends" of mine invited me to a house later in the week to drink, eat and hookup with girls they'll invite. I have never done this. I've hooked up with girls but they knew me, they had some semblance of an idea of who I was.

These girls don't and honestly I have no idea how to act or be. What should I do or not do. I have never approached a girl in this kind of scenario so I'm totally clueless. What are some tips y'all can give me?
