Baauer released Harlem Shake in 2012, and it became a global dance meme in early 2013 when short videos copied the same pattern of one lone dancer followed by a room full of people dancing wildly after the beat dropped. The intro became instantly recognisable as the warning that the chaos was about to start, which is why creators still use it as a nostalgic setup cue. Its short length makes it easy to drop into edits, reaction videos and throwback compilations that reference the early viral video era.
