I do agree with slightly rejecting her at the outset, however I want to caution anyone thinking about using this technique to keep everything light and playful, as Bartek suggests.
Some chicks don't take rejection very well, and even the best looking girls can have egos made of glass.
You want to make sure that you don't go overboard with your initial "rejection".
I agree that initial "rejection" works wonders.
Last night someone brought this chick to me and asked me, while she was listening, if I would have sex with her. I looked her up and down, made a gesture with my hand indicating "so-so", and said "I don't know, maybe", as if to say that I would hit it only if intoxicated or desperate.
She was visibly brought down a few notches by my comments, but then I wrapped my arm around her waist, gave her a kiss on the cheek, and told her "Of course I would".
She loved it.
