How can I get a hook up at this party?

im going to what will be a really wild party on saturday night, full of all sorts of illegal things. there will also be about 60 people mostly gils, mostly older (18/19/20) and mostly slutty. im 17 and im a virgin, im not hopin to have sex but a makeout session would be great, but how do i get one? i mean just because a girl is drunk and a bit easy doesnt mean she will automatically sleep wth me
