The booty bounce comes from lots and lots of practice. i am always bouncing up and down and one day i was bouncing so hard that i heard a noise which later i perfected into my booty clap. practice practice practice :)
My parents do know that i am in the industry and i was the one who filled them in on my new career choice. They took it a lot better than i expected but ultimatley they wish i would do something else but respect my decision.
