Etymology
From halitosis + -phobia.
Why this word is great
HALITOPHOBIA — [Noun] A morbid fear of having bad breath. From halitosis (Latin halitus, "breath") + -phobia (Greek phobos, "fear"). Unlike "halitosis" (which names the condition itself) or "pseudohalitosis" (which describes a false conviction of it), halitophobia is the gnawing dread that lingers even after mints, mouthwash, and reassurance. It is the compulsive cupping of hands over one’s mouth to test the air, the subtle recoil of a conversation partner mistaken for disgust, the way every polite step back feels like condemnation—a quiet terror that the self, in its most intimate emission, is unwelcome.
