A young motorcycle rider caught the tail end of a heated exchange between him and a Miami Beach police officer on video, where the cop says he'll "be fucking a bigger bitch" if the kid messes with him. Whatever that's supposed to mean.

YouTube user Albert Valdes uploaded this video on Monday, and only shows the end of the confrontation between him and officer Kenneth MacLeod of the Miami Beach Police Department.

Per Talking Points Memo, here's how the conversation went:

"You want to be a sarcastic bitch? I'll be fucking a bigger bitch," MacLeod said. "You're fucking with the wrong dude, bro. I've been here longer than you've fucking been alive. I've put up with more shit that you can ever think of. So if you want to test me again, you'll be finding Dade County Jail real fucking hunky dory tonight."

It's not clear what initiated the traffic stop in the first place. Valdes says the outburst was sparked after he said, most likely with a ton of sarcasm, "God bless you" to the cop.

A detective told the Miami Herald that they are investigating the video, and said "the actions of one officer does not speak for the whole department."
