when Harlem shake was a thing

The Harlem Shake was a viral internet dance trend that gained massive popularity around 2013. It involves a short video where a group of people, often wearing costumes or using props, dances to the song "Harlem Shake" by Baauer. The videos typically begin with one person (often wearing a helmet or mask) dancing alone in a seemingly ordinary setting while the song's initial bass-heavy beat plays in the background.
