Twerking is a type of dance in which the dancer, usually a woman, shakes her hips in an up-and-down bouncing motion, causing the dancer’s buttocks to shake, “wobble” and “jiggle.” According to the Oxford Dictionary Online, to twerk is “to dance to popular music in a sexually provocative manner involving thrusting hip movements and a low, squatting stance.”
The moonwalk is a dance technique that presents the illusion of the dancer being pulled backwards while attempting to walk forward. A popping move, it became popular around the world after Michael Jackson executed the dance move during a performance of “Billie Jean” on “Motown 25: Yesterday, Today, Forever” on March 25, 1983. This special was broadcast May 16, 1983. It subsequently became his signature move, and is now one of the best-known dance techniques in the world.
Grinding — known as freak dancing or freaking or, in the Caribbean, whining — is a type of close partner dance where two or more dancers rub or bump their bodies against each other. A more explicit form of the dance is known as daggering. Grinding gained its initial popularity in night clubs, and eventually moved on to high school and middle school dances especially in the U.S. and Canada where there have been cases of administrators attempting to ban it due to its explicit nature.
The Worm — sometimes referred to as the dolphin or the caterpillar — is a dance motion often associated with breakdancing and “funk” subculture in which a subject lies prone position and forms a rippling motion through their body, creating a wave reminiscent of a worm crawling. This can be done either forward or backward, by shifting weight from the upper body to the lower body (backward) or vice-versa for forward. The worm was performed at some punk rock shows in the 1970s, was popularized widely during the 1980s “funk” period and continues to be associated with breakdancing.
The robot (or mannequin) is an illusionary street dance style — often confused with popping — that attempts to imitate a dancing robot or mannequin. Roboting gained fame after Michael Jackson used the dance when he performed “Dancing Machine” with his brothers, and later performed the dance during his solo career in songs such as “Billie Jean.” When done without music it is considered to be mime, instead of dance. Street theatre often featured mimes who did a mechanical man or puppet style illusion, without music. In the late 1960s, the style was used while social dancing to funk or soul music.
