Pro MMA fighter Josh Koscheck is so powerful -- dude can take a helmet right from a bike cop ... and get away with it!
Last night, the UFC badass hit the L.A. bar scene -- hard -- and on his way out, dude startin' jokin' around with some cops outside one of the watering holes. Josh thought it would be funny to "borrow" one of their helmets ... but they weren't laughing.
Afterwards, Josh started trash-talking his next opponent Georges St-Pierre -- predicting he will "knock his ass out!"
That dude Kos was hanging out with had his nails painted and he was wearing a suit... I bet they sit at home and paint each other nails. I was a decent fan of his until I saw this, he acts like a complete moron.
