So my question is fairly simple, in the club on the dance floor girls are usually grouped with 2 or more. When a guy starts dancing/grinding behind girl 1 and she is receptive, girl 2 sometimes says something to girl 1 essentially saying ‘don’t do it’ and then girl 1 stops and they move away and the guy moves on. I’m just curious as to what girl 2 sees to decide that. Is it looks, smile, vibe, all of the above?
