Shuffle is a rave dance that developed in the 1980s. Typically performed to electronic music, the dance originated in the Melbourne rave scene, and was popular in the 1980s and 1990s. The dance moves involve a fast heel-and-toe movement or T-step, combined with a variation of the running man coupled with a matching arm action. It's an improvised dance and involves "shuffling your feet inwards, then outwards, while thrusting your arms up and down, or side to side, in time with the beat".
It seems to be a minority underground dance without official competitions or schools. Given the music, it's origins and the energy it requires, most of the videos are uploaded by young people that reproduce the nasty gender roles that the society embeds in us. So expect to see over sexualized girls and over testosteroned guys, which is sad.
It's the original shuffle, which was the one that caught my eye several years back with Francis' video:
It's "simple and straightforward", the base is the running man, with a few kicks and spins sprinkled in from time to time, so there is not much room for variety. It has a low skill floor and a moderate skill ceiling.
Usually the dancers wear trousers with a wide end that makes a nice flying visual effect and a hoodie. The percent of read women Melbourne shuffle videos is low.
Although in the source post they say that these styles are usually danced between 150 and 200 bpms, I've found that the videos range from 130 to 160 bpms with an average of 150 bpms.
It's the most popular right now (at least for the number of videos I've found). The base steps are the Charleston or the heel variants of the running man, which looks less like running. The basic step is used less than in the other styles, filling most of the moves with heel-toe movements, criss-crossings, and spins, so there is little "shuffling" in cutting shapes. It has a low skill floor, but an absurdly high skill ceiling. There is a lot of room for variety and you can even mix it up by adding other dance styles to it, as it's very flexible.
Usually the dancers wear street clothes and some use shoes with led lights. The percent of read women Cutting shapes shuffle videos is even with read males.
Cutting shapes songs are mostly around the 130 bpms.
