(9/20/2010) Now the U.S. is known for making some silly ass dances, but this clearly the craziest dance ‘craze’ I have ever seen. It involves a little…no, a lot of bumping and grinding, then…you head butt the booty. Right. Â Then you chest bump the booty, and hit it with your shoulder, then you kick and knee the booty,…and bump hips like you are doing the butt, then go back bumping and grinding. Then the man and woman switch positions, and she gets her grind on. I am not making this up. Look, I thought the ‘Flex’ was a retarded dance…this is retarded plus a work out. Check it out and let us know what you think!!
