Shaquille O’Neal
‘Shaq’ was unstoppable on the court during his heyday with the Lakers. But he was also a relentless trash-talker and targeted everybody that crossed him. This included rivals like Patrick Ewing but he also went after his teammate, Kobe Bryant. O’Neal and ‘The Black Mamba’ played for the same team but they resented each other.

Meanwhile, O’Neal continues to prove that he’s a master troll. He famously went after Oprah after she joined Twitter and targeted many other celebrities. The big man enjoys having fun but he rubs some people the wrong way. Most people love it when Shaq talks trash because he does it with a smile on his face (via Bleacher Report).
