I've never read The Game or any of that, but My Brother had a friend who used to go round basically, and I mean basically every single Girl in a Nightclub and try his luck. If she didn't fancy him, he'd just move on, and it did work to a certain extent. Yeah, he wasn't fussy about who he went home with sometimes it was 10 tonne Tessie and also he'd get the Stunners as well at times.
He had been with a long-term Partner for years and then she broke up with him.
It would only work in a Big Club though. Although, it does look fairly pathetic seeing someone go up to a Girl and chat for a bit, and then just move 10yards to another Girl, and then on and on til one snogs him.
You certainly need Confidence to do that. If you get up tight about being rejected by Women then it's never going to work, but some people can just shake it off and literally move onto the next one.
I'm nothing like him though. If I was rejected, I took it as a personal thing etc, especially when I was a lot younger, but now being a bit older.. (I've been in a realtionship now for 5years) but you certainly some type of self confidence, hell some might say arrogance to just move from Girl to Girl getting rejected before finding one.
