So I'm very late on this craze but that's okay. Here's the background: There's a movie called Weekend At Bernies II and it features this dude, Bernie, that has that same exact posture and movement that you see above. I must say that this could be the funniest thing I've ever seen just because there's a real song to go along with the "dance" and I was in tears while homeboy in the video was moving like Bernie everywhere he went. Just check it out, laugh if you need to and if you see me moving like Bernie then you know why. "Hold your head back like a nosebleed coming through."
Catch that right here as well.
