Fish-mouth Syndrome is a condition that infects most of the SJW community. You can tell if someone suffers from this just by their upright-triangular-frowning mouth appearance (which also exposes the front incisors). This facial expression gives the infected person a stink face, with subtle hint of mental retardation.
Patients with FMS (abbreviation for Fish-mouth Syndrome) often have attention seeking hair styles/color, wear nonprescription glasses, and have at least one body piercing. They are easily triggered, which prompts them to uncontrollably defecate from their mouths.
Cure: Common sense and more exposure to the real world.
