I've seen that somewhere recently, but I can't remember
where! !

The shuffle dance, also known as simply the shuffle, is a rave and club dance that developed in the UK during the late 1980s. Many of the movements used in shuffling are typical jazz dance steps but with a contemporary twist. The style is also influenced by a Chicago-based ghetto house dance called footwork and a style called the Crip Walk that originates in Compton, Los Angeles, United States in the 1970s. The basic movements in the dance are a fast heel-and-toe action with a style suitable for various types of electronic music. Most variants also incorporate arm movements.

No one knows the origin of the shuffle as rave or party dance moves. Indeed it's not clear if the dance was developed well before the name or at the same time. The earliest video evidence of the shuffle as rave dance moves on this page is currently from the UK. Anecdotally it does not appear to have a name at this time in the UK and was just a common set of dance moves found at UK raves and parties of this era.

The Running Man Dance Move

The running man dance move predates house or rave shuffle dance moves. It appears later it was incorporated in to a set of moves commonly seen at raves and parties.
