A new stupid dance crass on YouTube, and people just making idiots of themselves. Usely only about 30-45 seconds long, where it starts out as one person dancing and everyone not noticing. Til about half way and then everyone in the room dances and shakes usely masked to hide their shame.
Did you see Jimmy Fallon on YouTube doing the Harlem Shake?

Yeah they all looked retarted!
