It is true...if you can look at a hot chick and tell yourself in your mind that 'she's your sister...she's your cousin'...and make yourself temporairly believe that while they are in your company or possible conversation then you're golden. You have that advantage over them.
You would talk to them and act around them no different than if they were your sister or cousin or something and it would freak them out and they would be blown away by the fact that they are being treated 'without an agenda' because they are so used to and bored with guys trying to 'holla at them'.
When a woman is thrown off by a man...when a man does the opposite of what they expect...it confuses them and their brains cannot handle the system overload so they only way a woman knows how to bring balance back to her equilibrium is to sleep with the very same element that shook their world up. It's so so simple.
Remember when George Costanza(Seinfeld) decided to do and be the opposite of everything he has ever done? Remember when he decided to treat women the opposite way he always had? What happened? When asked 'George Costanza who are you?

?' he replied ..."I am the opposite...of every man...you have ever met".
Food for thought young players...best way to get in bed with a hot chick is to ignore them...let them feel or see you in the room but look upon them or treat them like they are nothing but a dime/dozen to you...make them feel you KNOW their shit stinks and make them feel you are not that impressed by their looks...watch the things fly off and watch the text messages on your cell phone triple...past 10pm.
