Some highly controversial things have been said during the Mayweather vs. McGregor world tour, but "Money" may have taken the cake during the tour's final leg.

For months now, the talk of the town in the combat sports world has been the arranged boxing superfight between UFC lightweight champion Conor McGregor and undefeated 49-0 boxing legend Floyd Mayweather Jr. The pair are set to meet on Showtime pay-per-view (PPV) next month on August 26th from the T-Mobile Arena in Las Vegas, Nevada.

To capitalize on the momentum of the bout, a four-stop World Tour was held to allow the combat sports mega-stars to get on the mic and let each other know how they really feel about the other. The tour included stops in Las Angeles, Toronto, Brooklyn, and London, which featured boxing-esk press conferences that really took "The Notorious One" out of his element initially.

McGregor's unfamiliarity with the scenario really showed in the tour's first stop, as he made his way to the stage way too early as well as not being prepared to make a speech of sorts before allowing Mayweather to take the mic and go off on the Irishman.

Many began to label McGregor as a racist for calling Mayweather, a man of color, 'boy' as he was dancing on stage. While that stole headlines for some time, the attention immediately shifted to "Money" on the tour's final stop after the boxing stud labelled McGregor the homophobic slur of 'f*ggot.'

Mayweather has taken a ton of heat for using the term, however, "The Notorious One" isn't holding it against his counterpart too harshly. When asked for his opinion on Mayweather's actions, McGregor claimed to have not even heard when Mayweather used the term, but believes people have been way too sensitive with the words they've used throughout the tour (quotes via LowKickMMA):

“I actually didn’t even hear that,” McGregor said. “People are so touchy on words. It’s absolutely crazy,” McGregor said. “If he said that, I couldn’t give a (expletive). I think what he was trying to do was to switch it up and get the people back in his favor. I think it was a bit of a (expletive) move to try and instigate that on me.

“Everyone with a sane mind that is watching knows what way it is. It is what it is. Some dirty tactics out there, but that’s what to expect. The fight game is a ruthless business.”
