Paul Pierce was in attendance at the TD Garden as the Boston Celtics defeated the Golden State Warriors in Game 3 of the NBA Finals, 116-100. Amid his post-win celebrations, The Truth spotted a couple of Dubs fans in attendance. Pierce wasn't too pleased with how the visiting fans were acting after the game so he made sure to send them an NSFW message.

Pierce was on IG Live celebrating the victory right after the game. The Celtics icon was sitting courtside and was providing some real-time footage of the developments right after the final buzzer. This was when the Hall of Famer saw a couple of Warriors fans in the crowd. His reaction was priceless:

After screaming at them to sit down, Pierce called the Warriors fans “f—ing idiots.” Talk about an unfiltered reaction, right? This is the type of stuff that makes Paul Pierce a Celtics legend.

The former 10-time All-Star was clearly over the moon following Boston's huge Game 3 win. The Celtics are now 2-1 up in the series against a powerhouse Warriors side.

Pierce won a title for the Celtics many years ago and he's obviously hoping for a repeat this year. Right now, Boston is in a great position to achieve this ultimate goal.
