Robin Lopez has maintained a healthy feud with many of the NBA’s mascots over the years. On Sunday, Lopez added the Toronto Raptor to his list. While wearing a wig bearing a strong resemblance to Lopez’s luscious locks, the Raptor began doing the most disrespectful thing he could think of.

He shimmied.

Lopez reacted in turn.

An underappreciated aspect of this video is the reaction of the game’s referee, who refuses to acknowledge Lopez, the mascot, or any of the chicanery occurring around him.
