VIDEO: Take 20 seconds to watch one of the nastiest spinning back elbow KOs of all time

Don't get on the bad side of Chris Mauceri.

Actually, don't get on any side of Chris Mauceri because, as we learned at Friday night's Lion Fight event, the welterweight can finish a fight from ridiculous angles. Mauceri produced a very serious candidate for Knockout of the Year when he landed a spinning back elbow to the jaw of Nicolas Parlanti in the third round of their Muay Thai bout.

Wow! Nasty ko by Chris Mauceri! Poor guy got stretchered out but he's ok. Congrats guys! @Muay_Thai_Guy #LionFight24 pic.twitter.com/GXYkPqwQwY

It was Parlanti who first attempted to throw the technique but he may regret putting that idea in Mauceri's head as the New Yorker spun his hips and landed flush with the point of his elbow and Parlanti was unconscious before he hit the mat. Ouch!
