Mutt

This is a common slang in South Florida that means to be doing too much. Generally this excessiveness is followed by either feeling like a bully or that you overreacted.

If you mutt often you’re either a very scary person or you feel a need to defend yourself often and overdo it. Also, if somebody says you mutted then they most likely would want you to stop that behavior.

Ex 1:
Person 1: Yo did you hear Josh shot that gas station clerk dead during the robbery.
Person 2: Damn what’s wrong with Josh, that man mutted.
Ex 2:

Person 1: I’m gonna talk to Ian since I don’t like how he was speaking to my girl.
Person 2: Alright that’s fine, just try not to mutt and start something.
Person 1: Shut up, he was talkin to my girl, I’ll mutt if I want to.
