He was caressing himself and shaking his ass at the audience, of which I am a part, since I am watching the thing. Do you really want to argue semantics?
LOL, it's all good man, I think dancing like you're a stripper in front of a room full of (I can only assume) mostly dudes is fucking gay. That is all. You're not going to dissuade me from that opinion.
They probably don't think of it that way, and I'm not saying bodybuilding or bodybuilders are gay.
If I were in a room full of chicks I'd be doing the same shit. So it's not so much WHAT he's doing, it's WHO he's doing it for.
I can still appreciate an awesome physique, even if the dude is moving like he wants a $20 stuffed down his trunks.
OH, ONE MORE THING: Arnold and Franco were learning how to move gracefully between poses at the beginning of Pumping Iron. There were no "dance moves" involved.
