Conor rose to fame as a mixed martial arts fighter.
But he's been challenging title-winning boxer Floyd Mayweather to a match for years.
Now Floyd has come out of retirement to fight Conor, and the trash talking has reached epic proportions, with each side finding new ways to disrespect each other on a daily basis.
Conor is clearly here to make a spectacle of himself, and he's succeeding.
Conor even wore a pinstriped suit to one of their meetups, which was printed with a tiny "F**K You" pattern.
He makes flashy Floyd look subtle by comparison!
Other times he barely even bothers with clothes at all!
And of course, he has no problem playing into stereotypes to amp up interest in his fights.
