In addendum:

What Mr. Hotpants should have done:

Guy: Do you want to dance?
Girl: Yes.
Guy: dance

Note: No tits or pussy grabbing involved! Holy shit!

Guess what? I dance with my friends all the time, including friends whom I ended up dating later, and they don't fucking do that. Oh wait, I forgot, they aren't so sexually repressed or dysfunctional that dancing means fuckfuck time.
