I always like the ballsy/direct approach over the indirect stuff. Maybe it's because I'm good-looking, but that always seems to work out okay for me. If she's drunk, it'll be easier to fvck her. What you have to do is isolate her from her friends (like on a couch or something) and start playful bantering. Make sure there's like, raucous laughter all over the place. Then, do some kino escalation, and if she complies with your kino escalation, keep the conversation going and keep her entertained (I hope you know how to multi-stack.) Then, first say "man, I would so fvck you tonight but you're just bein' an @$$hole." At this point, she'll either do one of two things:
1. Give you the deadpan because of the awkward nature of what you just said.
2. Hit you playfully on the arm "noooo, I'm not being an @$$hole, you're being an @$$hole."
This only has like, a 20% success rate. What you then want to do here is start playing with her hair, make sure she's comfortable that you're putting heavy moves on her. If she is still receptive to your touch, use one of Mystery's lines: "I'm trying so hard not to kiss you right now."
If she is still playful with you, teasing you, blah blah, tell her to "shut up for a second" and look deep into her eyes and start stroking her cheek. If she looks into your eyes and doesn't stop as you move closer to her face, BAM, you can kiss her. You have to make sure you have conveyed sexuality before you do something ballsy like this though, I'd suggest reading Gunwitch Method.
Well, this'll get you making out with her. I've never gotten successfully past this point to the bedroom, but that's what seems to work for me. Happy sarging!
