What is Twerking?
First off, here's the Wikipedia definition of twerking:
Twerking is a dance move that involves a person shaking the hips in an up-and-down bouncing motion, causing the dancer to shake, "wobble" and "jiggle." To "twerk" means to "dance in a sexually suggestive fashion by twisting the hips."
Now, perhaps a more urban authority will be more accurate. Here's UrbanDictionary's definition:
Twerking: The rhythmic gyrating of the lower fleshy extremities in a lascivious manner with the intent to elicit sexual arousal or laughter in one's intended audience
A Brief History of Twerking
The history of twerking proper dates back to 1993 when it was first used by DJ Jubilee. However, the term really only entered any kind of popularity when the Ying-Yang Twins released Whistle While You Twurk in 2000, which goes to show that 'twurk,' is an alternate spelling. Diplo, Juicy J, Drake and Wacka Flocka Flame have all contributed to the term's more recent wide use. However, universal popularization (the kind where your mom knows what twerking is) of the term has now recently occurred, of course, on behalf of Miley Cyrus, in her recent performance at the VMAs.
Twerking and 'Ratchet'
Some people think twerking is "ratchet," which may prompt you to ask: what does a tool in my garage have to do with twerking? A valid question for the pop-culture layman, but ratchet, in this context, is loosely defined to mean "ghetto," and by ghetto, it is really meant to mean trashy. As an extension of that, some have argued that twerking is less of a dance move and more of a basic human sexual impulse, since it closely mimics human intercourse.
Needless to say, twerking is here to stay as a cultural and physical force. It is probably stronger and more relevant than gravity at the moment.
