Kobe Bryant
The “Black Mamba” was among the most brilliant trash-talkers the NBA has ever seen. He dedicated himself to the cause and was cold in his delivery. Bryant famously went to the effort of learning French because he wanted to troll Tony Parker. He was also ruthless toward his teammates like Kwame Brown and Chris Mihm.

Modern icons like Kevin Durant and James Harden felt Bryant’s ire. He once said, “maybe one day they’ll sit at my lunch table.” Even LeBron James didn’t escape as Bryant made a scathing comment about the decision. He told him to enjoy his MVP win in whatever city because the Lakers were winning championships (via Complex).
