All you need to know about the Miley Cyrus/Robin Thicke “duet” at Sunday night’s Video Music Awards can be summed up in the horrified faces of Will Smith’s kids. (Correction: It was Lady Gaga’s performance that prompted that reaction.) Yesterday, the deep thinkers in the media went back and forth over whether the performance itself was racist or if calling the performance racist was racist. Now, two days later, ABC News is at work trying to explain the physiology at work in “twerking.”

No, really. “Twerking: A Scientific Explanation,” featured on the health section of ABC News’ website, claims that “only a Ph.D. researcher can explain how the body does what it does to make it happen.” Well? “You take a wide stance with your legs turned out at 10 and 2 so your hips are externally rotated. Then you pulse up and down as you thrust the pelvis bone forward and back.”

Fascinated follows latched on to the #ABCReports hashtag to predict the next scientific breakthrough from the ABC News team.
