“Why doesn’t Mike Tyson use a PlayStation?”/“Because he’s an X-Boxer.”

Xbox is a video gaming brand from Microsoft. Is someone who uses Xbox called an “Xboxer”? Of course, there are “ex-boxer” jokes.
   
“Why doesn’t Mike Tyson play PS3?......... - He’s an x-boxer” was posted on Twitter by Kristian Moon on January 13, 2010. The joke has also been told using the names of boxers other than Mike Tyson.
     
“I just got my son a flat piece of cardboard for Christmas. He wanted an ex-box” is another Xbox joke.
