When I would go to Las Vegas to dance (strip) I would watch the girls on stage and they would vibrate their asses in so many different way. I was fascinated with how they did that. I would go home and practice all day trying to shake my booty! I finally learned how to do it and went to work and did it on stage. It was a huge hit and made all kinds of money just shaken that ass! So watch as I bump dat butt to some tight tunes! LOL - Version for your IPOD!
