Just wait for 2014 xD
I has inside informations.
Ironically these the original versions of these dances first appeared 20 years ago.
1991: Leeroy Thornhill demonstrates a new style of breakdance that originated in Essex (UK) with The Prodigy for rave music performance, this is said to be the origin of the melbourne shuffle.
1992: New styles of jacking and vogue emerges in America that was seen as less gay (
modern club music comes prominently from the gay community and wasn't always favored by non-gays), such was performed to dutch/tech house and the arising moves later also gave grounds to industrial dance that was danced to hard/EBM dance music and later electro house as tecktonik as well as several fad dances.
1993. Miami bass, ghetto tech and booty house dances emerge as crazes, music eventually because associated with heavy 808 basslines and faster beats that later became jungle / rave / drum n bass, celebrated largely among afro-american communities in the US.
2011: LMFAO seizes the appeal of the melbourne shuffle after it becomes largely popular to the Electric Daisy Carnival (EDC), especially after the Black Eyed Peas snaps up the appeal of the music styles surrounding this event, after LMFAO accusingly "steals" the dance, some EDC goers started to favor the candy walk (Baltimore Club derivative that was originally named the nordic track) but this is being replaced slowly with tekstyle dance as a reaction to Q-Dance going to EDC.
2012: YouTube hacker zb3 makes Gangnam Style famous after finding away to avoid captcha and haul numerous proxies, viral popularity caught on, song becomes the most viewed on YouTube with YG Entertainment's exploit of this; dance moves are jestfully performed variations of the house dances.
2013: Jerkin, chopped n screwed and ghetto tech infused track is released with the skanking moves derived from detroit during the miami bass era (largely publicized by DJ Uncle Al as "Party Rap" moves).
(I am losing faith in popular music...)
1994: MC Sar & the Real McCoy and Bobby Brown were largely regarded in this era for dance which was largely feel-good expressive house dance after Nu Soul and New Jack Swing (that were both counterfactually renamed contemporary R&

saw popularity with the celebration of chillout hip hop.
2014: May be something along those lines? "Feel good" keyword makes me doubt it somewhat, but popular music at the moment is largely minor and cheesy so a turn is somewhat possible.
