When I was young and going out clubbing we girls learned a rule from the older girls. They said if you wanted to dance and have a good time...simply say yes to the first couple of guys that ask you to dance. They said the other guys are watching and if you say no and get super picky, no man would really ask you to dance, they didn't enjoy being rejected.
So, I did that, sometimes with one or two of my girlfriends and their dance partners. We even mimicked the way they danced just to be silly. The guys never picked up on that...but we did get to dance for the rest of the night.
I don't miss those days though. I outgrew it long ago.
