10. Colby Covington Calls Brazil 'A Dump'
We may as well start with this generation's ultimate d*ckhead.
Colby Covington began his career in the UFC by quietly going about his work and letting his actions in the Octagon do the talking.
Then he was told that the UFC would not be re-signing him - win or lose - after his next fight with Demian Maia at UFC Fight Night 119 and something snapped inside of his head. If he wanted to stick around in the company, he had to drum up some attention... and he did just that after winning the fight via unanimous decision.
In the wake of his victory, Covington completely blasted the country hosting the event, labelling Brazil a 'dump'. Before that he even proclaimed that he 'should have knocked (Maia) out', knowing full well that Maia was fighting in his hometown that night and the fans wouldn't react well to this level of disrespect.
They didn't and Covington revelled in the chorus of boos which rained down on him in the middle of his post-fight interview with Daniel Cormier.
He soon became indispensable for Dana White and has routinely found himself in title fights (and the headlines) in the aftermath of this despicably villainous moment.
