Well, at least it’s not someone doing the Gangnam Style horsey dance. I’m over that.
These are your Portland Trail Blazer rookies, primarily Damian Lillard and Meyers Leonard, doing the Dougie as part of some on-court hazing by LaMarcus Aldridge and the Portland Trail Blazers. Lillard has got some moves. Leonard dances like a 7'1" white guy who played basketball at Illinois. Which is to say, not well.
Hat tip to The Big Lead for finding this.
