They can usually be identified using words like "supes" and "totes" which are easier for them to pronounce. See also Taylor Lamontism.

Taylor Lamont's small mouth syndrome was apparent as he made judgy facial expressions at the HRC Gala.

Small Mouth Disorder 

A rare yet serious disorder which gives the victim the appearance of a small fish such as a bluegill. It also makes it impossible for the victim to digest foods other than M&M's or raisins. Also known as Bluegillitis.

I often wondered why Craig looked like such a bluegill until I found out he had Small Mouth Disorder, or Bluegillitis.

There is little hope for those with Small Mouth Disorder. Poor Craig, they may never find a cure.
