MDR is a long running piece of French online slang, the equivalent of laughing out loud, and pairing it with Roi Artur gives the clip its mock royal character. Artur is the French spelling of Arthur, the legendary king widely parodied in French comedy and meme culture. Short laugh reactions like this spread through soundboards and messaging apps because they need no context, can be replayed instantly, and translate a written MDR into an audible reaction that works in videos, streams and voice messages.
