What is "uprock"

Uprock, or Rocking as it was originally referred to, also known as Rock, is a soulful and competitive urban street dance, performed in synchronization to the beats and rhythms of soul, rock and funk music, but was mostly danced to a specific and exclusive collection of songs that contained a hard driving beat. An example of such a song is the uprock classic "It's Just Begun" by noted jazz musician Jimmy Castor. The dance consists of foot shuffles, spins, turns, freestyle movements and more characteristically a four point sudden body movement called "jerk".
