Not only terms, but a ritual, too - hubby grew up with "popeye" in Kansas, and I had "padiddle" as a young person in Florida, but for both of us, when you saw a car with one headlight out, you were supposed to say the word, kiss your hand, and hit the ceiling of the car for luck. I knew somebody else who grew up with a different ritual - I can't remember if it was for seeing one headlight out or for something else, but everybody in the car was supposed to stick one hand and one foot out of the window whenever they saw whatever it was, including the driver!
