Just a couple hours after JuJu grooved to Popp Hunna's "Adderall (Corvette Corvette)" at Cincy's midfield ... PIT took one of the worst losses of the NFL season this year, falling 27-17 to the 3-10-1 Bengals.
And, to make matters worse for JuJu, he got LIT UP during the game -- fumbling a ball that ended up costing the Steelers big time.
Enter Sharpe ... who was so clearly delighted to see JuJu stink it up after dancing on the logo -- he took to Twitter to straight-up clown the 24-year-old!!
"Ju Ju might need a new car," Sharpe said. "That corvette, corvette isn’t fast enough to get away anymore."
