"Giannis might be a Pippen," he tweeted, obviously referring to Chicago Bulls legend Scottie Pippen. "There I said! He needs his Jordan."
On Thursday, Pippen caught wind of the tweet, and dropped the hammer.
"I'm not Giannis," he wrote, "I don't have back-to-back league MVPs (he will in a matter of days—and he’s not me. The question is... who were you as a player?"
Jay Williams also called LeBron James a "Pippen," prompting James to respond the following day.
"Explain to me what the fux I gotta do with this subject matter! I’m over here minding my damn business preparing for Houston," he wrote. "And by the way I ain’t never been nobody but my damn self!"

With the Bucks' latest loss, Giannis' future with the team could hang in the balance. In fact, it was reported earlier this week that he could even sign with Miami if they end up eliminating the Bucks.
But that's neither here nor there. For now, Giannis' focus is on proving to the world that he can lead a team to an NBA championship.
