Miami Heat swingman Jimmy Butler is not playing around. Butler got right in the face of Indiana Pacers forward T.J. Warren after Warren attempted to hook Butler's arm in an effort to prevent a drive to the rim.

Jimmy Butler clearly felt there was an element of dirtiness to the foul, as he goes right after Warren and is clearly screaming at him even after the two players are separated.

The four-time All-Star has never been afraid to mix things up throughout his career. Butler became an Internet meme after getting involved in the melee between the Philadelphia 76ers and Brooklyn Nets during the first round of the Eastern Conference playoffs last season:

He also tussled with LeBron James back when he was still a youngster with the Chicago Bulls:

Butler has reasserted himself as one of the best players in the NBA since coming to South Beach.

The 30-year-old entered Wednesday night's game averaging 20.4 points, 6.9 rebounds and 6.6 assists while ranking fifth in the NBA at 2.0 steals per game.

He has also played the role of feisty veteran leader for the likes of rookies like Tyler Herro and Kendrick Nunn as well as young center Bam Adebayo, who is in the midst of a breakout season. Butler has also spoken at length about his admiration for Goran Dragic, who he called one of his favorite teammates ever.

Butler has a reputation as one of the goofiest players in the NBA, but–as T.J. Warren found out on Wednesday–he is not to be messed with on the court.
