I realize that the title of this post doesn't really make sense. If you go to a bar or club and a ton of people are dancing, what criteria do you use/what do you look for before you go up and start grinding on a random girl? I was at a club last night and the place was packed to maximum capacity. For the life of me, I could not get a girl to smile at me. I was projecting good posture, had good body language, was making strong eye contact and smiling when I saw a girl I liked (and there were PLENTY) but I couldn't get a girl to smile back if my life depended on it. They'd look me in the eye then divert their eyes after about 1 sec. I'm not a bad looking guy but I felt absolutely ridiculous. I don't want to go up to some girl while she's facing the other way and just start grinding on her - I've seen that happen before and the girl will turn around, look at the guy, give a "no thanks" and walk off or push him away...
