Antonio Brown had to know he was going to be flagged for unsportsmanlike conduct and hit with a stiff fine.

But the Pittsburgh Steelers' star wide receiver didn't care.

After scoring a 29-yard touchdown reception during the third quarter of the Pittsburgh-Washington game on Monday Night Football, Brown proceeded to twerk in the end zone in front of the road crowd. 

Like really twerk.

Within seconds of the excessive touchdown celebration, Brown was flagged for a 15-yard unsportsmanlike-conduct penalty.

And his pockets will take a hit, too.

Ouch! 

Yeah ... hips gyrating and pelvic thrusts will do that for you.

But it was all worth it to Antonio, who wound up with 126 receiving yards and two touchdown catches in the Steelers' 38-16 win.
