chinny chin chin

Chinny chin chin appears almost exclusively in the phrase "not by the hair of my chinny chin chin," the three little pigs' defiant refusal to let the wolf in.

The playful reduplication emphasizes the chin, where a billy goat—or a stubborn pig—might sport whiskers.

Outside the fairy tale, the phrase signals exaggerated defiance or stubbornness: You want me to work overtime? Not by the hair of my chinny chin chin.
