Katt Williams is not the one to mess with, no matter the time or setting.

The comedian proved his no-nonsense reputation to be true when a troll tried to clown him out in public, claiming the Phantom he was driving was rented. What ensued afterward pretty much resembled an awkward stand-up rehearsal, as he went on a roasting session of his own.

In the video, which has since gone viral, Williams can be seen arguing with someone on the highway after they claimed his Rolls-Royce Phantom was rented.

In no time, the comic went into roast mode, calling the man in the other vehicle a "clout chaser" before adding that he's not XXXTentacion, who was recently tragically shot by burglars in Florida.

"Pull over and see what happens," he yelled at the troll who was driving beside him while hurling insults of his own.

Take look at the clip, below:

Is it safe to say Williams won this one?
