Teasing

As I'm sure you have noticed when doing your own approaches, there comes a time in the conversation where everything just comes to a halt. Whether you're done talking or she has nothing to say, doesn't really matter. What does matter though, if she feels bored she will walk away and it's your fault. Yes, yours. You are the man in the interaction, you need to lead the conversation. If she's not interested by what you have to say, you have lost the set.

To combat that, here's a small section of mid-game; specifically when it comes to teasing her... it will keep the energy up and the sexual tension charged. Teasing and challenging her will make you more socially dominant in the interaction. All these things need to be done in a PLAYFUL manner. Don't be overly serious or she'll start feeling uncomfortable.
Pick up something small (like a straw from the bar, a napkin, etc) and swat her with it. This works well when she did something stupid/silly

• Let something distract you every so often. While she's talking to you, let your eyes drift past her face to something behind her. Make her work for your attention. (Use this in moderation)
• Give her a cute nickname that's relevant to what she is/does, for example Dog Mommy, Coffee Goddess, Disney Princess, sparky, etc
• If she does something silly or doesn't play along (like you asked her to get you a lemon from the bar and she dropped it), be almost-too-serious and say, "I cannot believe you just did that. That's it, we're done."
• Mis-interpret things she does as being too needy and wanting attention, "You're moving a little too fast for me"
• If she gets sassy, tell her "You know, you're kinda cute and I'm almost starting to like you.... but you're really messing up your chances with me" (notice the weasel words here, *kinda* cute, *almost* starting to like you, etc)
• Treat her like your bratty little sister. Roll your eyes at her and push her away (gently) and say, "I can't deal with this, you need to go away"
• Find some random-looking dude that obviously has no idea about girls and go, "that guy right there looks perfect for you. Want me to go grab him?"

Hope this will help you guys out in the field :)
