One who has bad teeth and cannot afford a dentist. One who looks like he brushed his teeth with barbed wire. One who has so many gaps between each tooth he would need Gap Insurance to protect himself. One who cannot even spell Dentist so that he may go and get his chompers fixed.
One who has never been to the dentist, therefore the inside of his mouth looks like he brushed w Barbed Wire, therefore nicknamed ROCKMOUTH
