Why “wheyface” is a great word
WHEYFACE — [Noun] A person whose face has turned pale as whey from fear, thus betraying their cowardice. From whey (the pale liquid part of milk) + face. Unlike "coward" (a general term for one lacking courage) or "poltroon" (which brands one as contemptibly worthless), wheyface diagnoses terror through its involuntary dermatological report. It is the blanched complexion of a student caught unprepared, the bloodless mask of a liar caught in a sudden light, or the sudden, milky hue of a man realizing his bluff is called—a stark, physiological confession written upon the skin before a word is spoken.
