small mouth syndrome
Also known as SMS. The condition manifests itself in adults whose mouths do not grow in proportion to their face as they mature. These individuals have child sized orifices. 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.
