The most frequently used technique that I use in conversation is a kind of paper-rock-scissors technique. I basically study psychological concepts such as negging, rewarding, disqualifying, etc. For every move a girl makes, I have a counter-move that builds value. For example, if you were with me this weekend when I was talking to one of the blondes, then you saw that a part of my interaction went like this:
I see her dancing near me...
Me: "Are you square dancing? You're such an asshole."
Her: "Did you just call me an asshole?"
I notice that she looks pissed off like she is about to kill me. She is giving me a hardcore mean stare. I've been in this situation before, so I counter with a cold stare back. She asks me again, but I don't jump through her hoop...
Her: "I said did you just call me an asshole?"
Me: "Look at you, you look like you're about to rip my head off. I bet I'm a better square dancer than you."
I have effectively countered her by not jumping through her hoop and provoking her to ask me to do something...
Her: "Let's see."
I knew this was coming and already had the next counter-move ready. I don't show her, but instead make fun of how she was staring at me...
Me: "You were looking so gangster. Staring at me like you were going to do something." (and I make a retarded face)
She laughs, and comes up to me and hugs me tightly with her arms completely wrapped around me, and her face next to mine. I counter this by lightly pushing her away and saying...
Me: "You're nothing but trouble."
When she looks at me, I slowly turn around and pretend to walk away. She grabs my arm, pulls me back, and hugs me again.
