"There's one motherf***er in the jungle -- when he roar everything stops ... and I'm about to motherf***in' ROAR!"
You fired up yet?!
Cam Newton sure as hell is -- the Patriots QB just WENT OFF in a new gym session video .. and seemingly took a shot at his old team!!
While stomping around his gym, a shirtless, jacked Newton looks directly into the camera and says, "You gonna choose THAT over THIS?!"
Is it a message to his former team the Carolina Panthers -- who released Cam to later sign Teddy Bridgewater?
