Fowlmouth is one of the minor characters on the animated series Tiny Toon Adventures. He was a young rooster, voiced by Rob Paulsen introduced with a seemingly mellow personality but, as his name alluded to, had a tendancy to explode into bleeped out graphic cussing (note this was an censor done intentionally by the show's creators between lines of euphisms for the sake of humor) He was later cured of this habit per request (in order to score a date with Shirley the Loon) when his refusal to not cuss in front of children was exploited. This was particularly ironic given the target audience of the show.

He made slightly more frequent appearances later, revealing he was still somewhat pushy and rude, especially in movie theaters. He has since replaced cussing with the euphemism 'dang gum', probably replacing goddamn.

His mentor is, not surprisingly, the loud and pompous Foghorn Leghorn.
