Hello guys , I'm curious ,how you approach girls in the night clubs ?

Last week after a little break , I went back to party with some girls and some friends. Since I invited some cute girls , I had the chance to analyze and observe how girls react to guys approach.

Honestly I was really surprised to see that in 4-5 h they declined every guy who tried something . Most of them were stupid , using lame lines or using to much body contact, but I saw 2 guys , they had peacock style , and they were stalking around the room until one of them decided to approach the girl who was dancing with me. He offered his hand to her , and she grabbed my waist and turned me around so I block with with my back.

I'm curious why the girls acted like that ?!

And now , a dumb question when a girl is dancing back to back with you , or when she starts to dance in your lap , should you be more "agressive" and go for kinno ?!

I ask this because some times, I dance with a girl , we have fun , we sit down for a little and all the sparks are gone , and I don't get it if she's doing it just for fun or is it a sign ?

Can't wait to hear your answers, thank you for help guys !!! :D
