Apparently yesterday was a slow news day at ABC news because they found some one with a PHD to give a scientific definition of twerking.

Twerking is such a complex, technical subject, only a Ph.D. researcher can explain how the body does what it does to make it happen.
Twerking is a combination movement involving a deep squat and a pelvic tilt, Michelle Olson, a professor of exercise science and a certified strength and conditioning coach at Auburn University in Montgomery, Ala., explained.
“You take a wide stance with your legs turned out at 10 and 2 so your hips are externally rotated,” she said. “Then you pulse up and down as you thrust the pelvis bone forward and back.”

What makes this woman and expert on twerking because she has a PHD ? This doctor needs to find something worth while to research. Twerking is the result of the over sexualization of everything in America. There is nothing wrong with the actual dancing there is something wrong with the way we see it.
Some of the tweets I saw about this article on twitter were hilarious. [NSFW]
