Boxing fan screams brilliant insult at Floyd Mayweather during his ‘boring’ final fight (Video)

It was supposed to be Floyd Mayweather's glorious final fight.

'Money' eased to a unanimous points decision over Andre Berto to equal heavyweight Rocky Marciano's record of 49 fights undefeated. Yes he made history - but fans around the world weren't exactly bowled over by yet another 'dull' Mayweather shut-out. One supporter watching the bout inside the MGM Grand expressed his dissatisfaction in rather hilarious fashion. You can hear the guy scream 'What are thooooooooose?' presumably about Mayweather's punches. He yelled it so loud that the welterweight champion looks up mid-fight, and appears to shout something back.
