Miami Heat superstar LeBron James reportedly exchanged words with a fan during Friday's game at the Washington Wizards.

Bob Moore, a fan of the Wizards, told Deadspin.com that he heckled James, who in turn told him he would kick his (butt).

The fan started the exchange, according to the report, by making a lewd comment about former Cleveland teammate Delonte West and James' mother.

Moore told the website that James approached him and said: "The only reason you talk (smack) is because you know I can’t come off the court right now and beat your (butt).”

Shortly afterward, James added: “But if I had a free pass, I’d kick your (butt) right now.”

Moore said he encouraged James to come after him, saying: “I’m right here baby. Let’s go.”

At that point, Moore said security interceded.
