a redneck way of saying to work.

shaking your ass off while under the false impression that its hot

When a female twerks, she is repetitively gyrating her lower body. Famous twerkers include: Miley Cyrus, Nicki Minaj, Iggy Azalea.

A "dance" move that started going viral with a video with Miley Cyrus, it turned into a fad, where girls would make theyre own videos of them "twerking" and guys would make fun of them because of the way they "twerk" it has become a big fad to the point where your neighbors do it, your boss does it, you teachers do it, your pets do it, even your grandma can do it!

A word that has lost it's real meaning thanks to white people.

Twerk:

verb. To make one's labia's move from either one's vaginal muscles or air being pushed out. Also the rhythmic movement of the buttocks as a result of flexing a certain group of vaginal muscles (see Kegel) in order to create the labia movement made famous by strippers.

For some reason this has been diluted to the any dance that moves one's buttocks but is hilariously interpreted by anyone who knows the real definition, usually people from the south or inner city.

To go so hard during sex that you actually start to twitch.

Twerk, also known as bounce, grind, or wobble, is the rate of change of asseleration;

that is, the derivative of asseleration with respect to time, and as such the second derivative of ass-speed, or the third derivative of ass-position.
