OK I'm just getting started with this properly... but friday night i tried this and it worked like a charm...
Approach a group of girls with your wing (i did it in a line for a club, but you could do it in bar cues, coat room cues etc. or even approach a set in a booth) lift his top and say "Hey ladies, is this too much hair"... I guarantee they will laugh, and your buddy can just have the "WTF" expression on his face like he wasn't expecting it...
Its then really easy to steer a conversation towards "what you like in a man" and sex...
I'm going to field test this some more after exam period (im a student) and ill post the results...
Try it and let me know what you guys think
