Some more advice before 'the move'.
Try to watch a pro in action, not some fictional character off the television. Not particularly for any chat-up lines or such but just to see how easy it is to be confident around women without being a jackass. Make sure you don't get duffed up though...
Try to talk about her interests and such and find some common ground to talk about in a sensible manner, telling jokes and such. Basically its just like being with one of your homies except without the knob jokes. She'll probably want to talk about bands or what shes doing or some boring shit like that, just let her. Women like talking endlessly about trivial crap, if you pretend to listen then she'll love you for it. All you have to do is ask a few questions, if your skilled you'll be able to direct the conversation towards something interesting.
e.g. (THIS EXAMPLE SUCKS BUT IT DOES THE JOB)
female: I like barbie dolls. blah blah blah
you: Yeh, I think your right. How about that Ken though? You got one of those dolls?
female: Yes, blah blah blah.
you: Cool, hey do you think he could be Action Man in his spare time? like a secret identity? hehe
female: Hehe, yes that would be funny, blah blah blah action man
you: Yeh, Action Man rules
And if she doesn't laugh at the action man gag shes an idiot. Either that or your telling it wrong. Evaluate which and move on.
