I need some ideas for what late teen and early twenty girls discuss?

This is a covert operation that is part of a study for a class. I have to be able to talk to late teenage or early twenty year old girls in their jargon, or at least be able to understand their terminology.
I have ignored reality tv since it came out and now it seems like I should have paid attention.
Who is this Snooky person? Who is Tequila? She looks like a filthy whore to me, but apparently people like her. Is Big Brother “The” show to watch?
What is important to a teenaged girl? My youngest is eleven and can’t help me. My son is seventeen but is oblvious to the whole thing. He’s an honor student and has his head in his college/career plans. Any ideas about things of importance along with explanations would be greatly appreciated. Where do they like to go? What do they like to do? What drinks are popular now? Do they do drugs? Are they casual or conservative about sex?
