Push/Pull is whenever you emotionally push a woman away from you...and, then, emotionally pull her back in. Each Push creates an emotional space for each Pull. To get a sense of what I'm getting at, think, for example, of your favorite junk food. What if you went on a strict diet for several weeks, depriving yourself of giving in to your urge to eat your favorite food? What would it be like to finally give in to your urge and indulge? I'm willing to bet it would be more intense than if you hadn't gone on your strict diet, yes?
Many women are natural Push/Pull artists. Over the years I've heard dozens of stories from hapless men about women using Push/Pull to pick them up by the scruff of their proverbial neck, slamming their bodies with back-and-forth and side-to-side motions into the ground. My all time favorite story is the one about the gorgeous girl sleeping with a guy and then, after sex, putting his ego on steroids by telling him, "You're the best lover I've ever had." Things, then, alas, take a self-esteem crushing turn for the worse when she undermines her praise with: "Actually, you're the fourth best lover I've ever had." The poor bastard is crushed and he is, as if he were a little worker bee, struggling to move up to the number three slot.
We can use these psychological mechanisms without being an A-hole or a Jerk. The key is to make it playful and funny. Your intention should never be to hurt a woman. Your goal is to only mess with her a bit. Do this and women will find you charming and attractive.
