This is hilarious ... no one was MORE PUMPED about beating #3 Utah than the placeholder for USC -- who busted out the Drake dance, the LeBron and the Cam Newton during the game!

Check out the footage of Conner Sullivan just losin' his mind every time he successfully held the ball for his kicker ... dude goes bananas.

Our personal fave is the "Hotline Bling" dance ... but the Bron silencer is pretty solid too.

Next up Cal ... sooooo, hit the quan?
