Someone who has a foul or smart mouth.

This can be heard on That '70s Show by Debra Jo Rupp's character Kitty Forman.
Red: Oh, shut up, that’s it, I have had it! You know what this means? More discipline!

Kitty: No, no…

Red: Oh, yes. Play time is over.

Kitty: Oh, stop saying that! Your cracking down is not working.

Eric: Hell, I could’ve told him that a week ago.

Kitty: Now is not the time to be a Porky Mouth. Red, I want my house back.
