First off, this can and does work. I have done this before with random girls i either meet at parties/shows and or went to school with. If you used to talk to them a little then stopped for a while it works like a fucking gem. It works a hell of a lot easier if you look like David beckham though. Which i obviously know all about.
I feel like alot of these guys didn’t try that hard though… if you tell the girl you’ve had a crush on her and really get into it instead of saying something about clapping that refers to sex… i think they would have had much better results.
