Christine Stanley delivers devastating spinning kick for MMA knockout (VIDEO)

MMA fighter Christine Stanley delivers a spectacular spinning kick knockout that leaves her opponent flat on her back in the ring.

And it just may be one of the best the KOs of the year.

Although it was apparently recorded as a five-second knockout, amazingly, Stanley connected on the kick just 2.3 seconds after the bell. Her opponent, Katie Anita Runyan, hit the mat after 3.5 seconds, and the referee waved it off just under the 5-second mark.

Go ahead, say it ... you kick like a girl.
