Is this the most humiliating defeat for a world class fighter?

Remember Broner is coming on full steam of arrogance before the fight; proclaiming that he's the 2nd coming of boxing after mayweather is done. He really believed on it. Then the prefight arrogance that is too many and too much to mention, and finally during the fight itself he tried to disrespect his fellow fighter by trying to hump on him like a dog. Interestingly, he was humped back by maidana at the end of the round making him more sillier adding to the enormous beating he's getting as the fight went on. Not only that, this guy is trying to quit on the middle of the fight from a headbutt, he was hoping for a disqualification from the ref, a situation which he himself had caused by gripping two of maidana's arms hoping to hold on for his dear life. To top it off; as if not humiliated enough by the boos from the crowd after losing in a lopsided unanimous decision, people started to throw bottles at him during his cowardly exit.
