So if you run your mouth, get jaw-goned
As he explains in his next line, this a double entendre.
At one point he literally means he’ll remove your jaw from your face with a twelve gauge shotgun if you talk shit.
He may also be playing on the words ‘run’ and ‘jaw-goned’ because it sounds like ‘jog on’.
Word play in a Double Entendre! Mad skill.
