Big win means big dance party for the Chicago Bears -- who broke out the disco ball in the team locker room after beating the brakes off the Bucs ... and TURNED UP!!!
It's become a tradition for the Bears -- with head coach Matt Nagy believing his players should be able to celebrate the hell out of every victory.
So, after Mitch Trubisky and company dominated Tampa Bay in a 48-10 ass whooping at Soldier Field ... the ball came out and the music got loud!
The song -- "My Dawg" by Lil Baby.
"Great team victory. Unbelievable team victory," Nagy told the team after the game.
"That's a full team win right now and we protected Soldier Field."
The Bears get a bye this upcoming weekend -- before taking on the Miami Dolphins on Oct. 14.
