What's the Golden Rule? Never challenge or mess with an MMA fighter. Under any circumstances. Ever.
Another rule of thumb is you should definitely NOT challenge UFC Women's Bantamweight Champion Ronda Rousey.
One idiot reporter, however, let his pride get the best of him, and he had to learn the hard way that Ronda Rousey ain't nothing to f*ck with.
Why this dude would ever question why they call her "Rowdy" is beyond me, but he had those broken ribs coming to him.
