i dont think it's so much of being a jerk, but just showing that your are comfortable around the female of the species. After all, they aint nothing special, they sh!t in the same pot that i do.
like dirtheart says, it's because they seem to have it together, they seem to know what they want, and they know how to go about gettin it. Not because in their mind they say: oh, this guy's being a pric, i wanna bone him hardcore
This is my secret, i treat all girls exactly the same way, as if they were my sister, but with privileges of course
It may sound sick, but when i get in this mind frame, for some reason i feel much more comfortable around a girl i just met, and i can let myself go. It's easier to be CF, and to tease them, and when i get in this mind frame, they feel more comfortable around me too.
FOR THE RECORD, i dont have a sister
