You've likely landed at this article looking for one of two things. Number 1: an explanation of what this " Harlem Shake" thing is. Number 2: To see more Harlem Shakes!

We've got you covered with both.

Technically, the "Harlem Shake" was a dance move from the '80s. It began in New York's Harlem, and was popular in music videos. Then, in 2011, it was the title of an electronic song produced by Baauer. Now, in 2013, the song has become the track of many viral videos.

It seems to have started with the video below. The video of people wearing masks and dressed in latex suits, one in a Power Ranger costume, was uploaded to YouTube on Jan. 30, 2013. As you'll see in the video, which has been viewed over three million times, everyone dances.

But the dance and the video premise evolved. A YouTube user by the name of TheSunnyCoastSkate uploaded a video in which everyone around him was just going about their business while he danced to the music with a motorcycle helmet on. Then when the lyrics start, everyone else starts dancing.
