Floyd Mayweather Jr. is one of the world's biggest sports villains thanks to his money obsessed persona and history of domestic abuse. The undefeated boxer recently dropped a big chunk of money for four courtside seats to Game 5 between the Golden State Warriors and the Memphis Grizzlies for him and his entourage. When shown on the jumbotron at Oracle Arena, Mayweather was booed mercilessly by the crowd.
