The second-round series between the Washington Wizards and Boston Celtics has been filled with trash talk and a lot of posturing by both teams. Both teams simply don't like each other and that mentality is apparently spreading to Wizards fans.

During one of the games of the series, a fan was heckling Isaiah Thomas while he was on the bench. Not appreciating the noise, Thomas cursed out the fan.

It is unclear what the fan said to Thomas but it clearly set him off. The NBA doesn't take too kindly to players negatively interacting with fans but since this is a somewhat random cell phone video, Thomas may not receive a fine.
