After her victory on Saturday against Sarah Kaufman, bantamweight champion Ronda Rousey proved once again why she is indeed the best pound-for-pound female MMA fighter in the world.

In just her 1st title defense, Rousey beat her respectable opponent in a mere 54 seconds, which incredibly made it the 8th time in her career that she's finished someone off in less then a minute.

Upon landing three jabs and a right cross, the Strikeforce beauty defeated Kaufman with her signature submission arm bar to improve to 6-0 in her professional career.

Amazingly, many experts had thought that the now 15-2 and extremely challenging Kaufman would deliver the star her biggest challenge, but they were clearly mistaken.

The 25-year-old is said to have gotten the idea for the painful lock from her mother Ann Maria Rousey DeMars, who previously had a successful Judo career in the 80's. The equally tough mom gave her offspring the idea for the move by repeatedly waking her up every morning with it.

Rousey has been just as infamous with her words as she is with her fists. Aside from trash talking her opponents, she had recently spoken out negatively about reality star Kim Kardashian's fame and Olympian Michael Phelps' special celebrity treatment, amongst other things.
