Ah, there's a classic dilemna. How do you get the attention of that girl that all the guys want?
It's funny because every time I hear a pickup guru talk about this, he just hangs around her, doesn't kiss her ass, and suddenly she's all over him. Lol. This can work, but it's no sure thing.
Supposedly this works because the girl is so used to getting male attention. Then she sees you not giving it to her and she wonders what is wrong and starts seeking validation from you. Problem is, once she gets it, she has what she wants. Keeping the interest of a girl with that many options is tricky.
The trick is engaging her without kissing her ass. I hate to get all generic here, but teasing, kino, C&F, remembering that you are the prize, those are probably your best shots.
In this day and age with the internet and "game" becoming more mainstream, I foresee a future where it will be harder and harder to set yourself apart, because everyone is going to know all the tricks. So everyone is going to be going up to her touching her, and laying on the C&F. You ever see some guy when it is obvious he is running this type of game? Ugh.
