Rhonda Round Mouth 

Rhonda Round Mouth does not refer to any specific individual. Rather, Rhonda Round Mouth is a slang term which may be used, at will, to reference any female that is known to be a frequent provider of fellatio. The term Rhonda Round Mouth implies that the individual provides so much oral sex that their mouth is literally in a constant state of being open and round because of the constant inhalation of cock.

Fish-mouth Syndrome 

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.

Barista: Welcome to Starbucks ma'am. How can I help you?

Fish-mouth Syndrome patient: Oh my god! Did you just assume my gender? How dare you?! I refuse to be oppressed by your white cis male privilege. I will boycott all coffee from now on since you offend me so much. RAGE RAGE AGAINST PATRIARCHY! Now if you would stop harassing me, I have a pitcher of male tears to consume. Check your privilege.
