Pick up her habits or stuff; e.g. if she uses "like" a lot, you do to...
So it's like; you use the word's she uses the most, but not in a way that, like, makes it seem like you're negging her, but more just picking up whatever habits she has.
If she uses slang, adopt this as well... It's like you're beginning to fit her model of the world better, and she'll just feel like you're like... so getting her, like.. you know... .like you know exactly how she feels.
Even hand-movements, gesticulation, etc.
If she has stuff she uses constantly, you can do this, but make it seem natural, not like you're trying to mimic her and make fun of her.
Or you can put on her energy-level and pace this, following her energy-level and stuff. This will build rapport; and if you're so inclined you can gradually turn over to leading; increasing or decreasing the energy-level, turning the context of the exchange over to more sexual/seductive, or romantic subjects...
She will even pick up on it if you're not even talking about it, but just imagining you and her in the most intimate, arousing situation you can think of. Even if you're talking about the weather, the way you talk, and the way your word's flow over her will be flavored by the thoughts you're having.
Following or pacing can help build rapport;
But you can also lead the whole show, Which I think is far more intriguing for the girl; If you have a strong enough frame, and even make a frame for her. If you from the beginning of have such a strong frame that she finds herself slowly adopting what you do, and say, I think it has a much more sexy effect.
You're the guy they want to be like, you become the diamond, and as you know Diamonds are a girls best friend =P
You can establish the frame for her even;
if you consciously think she is <b>the</b> most sex-crazed kitten she will unconsciously pick up on these signals, and gradually she may begin to actually act out this frame that you have put her in...
It'll also subtly change the way you speak to her, and you'll often find yourself teasing her for constantly thinking dirty thoughts, and stuff like this
this is probably outside the original theme, but You can put it to good use ;P
I just can't seem to keep it short =P
