Saweetie Sexy Dance-Off With Mascot ... At Clippers Game

Saweetie tapped in for an epic dance-off with the mascot at the Clippers game on Thursday ... droppin' low and shaking it in front of the whole arena -- and TMZ Sports has the vid!!!

The stars flocked to Arena to watch the Lakers get wrecked by the Clips ... with Justin Bieber, Rami Malek, Normani, Israel Adesanya and more getting a front-row seat for the matchup.

But, it was the "Best Friend" rapper who ended up stealing the show during the 4th quarter ... getting up and dancing with Chuck the Condor as "Conga" by Gloria Estefan blared over the speakers.

Check out the vid -- the fans in attendance went nuts for the spontaneous dance competition ... with folks cheering and whistling as it unfolded.

Safe to say Saweetie came away with the W ... but you can't say that about the Lakers, who stunk up the place once again in the 132-111 defeat.

The Lakers are now 27-35 and have lost 4 games in a row.

But, look on the bright side, at least the Clippers fans had a good time??
