"Hubba hubba, 23 skidoo,oh you kid, the cats pajamas" and the ever popular "she'a a real doozie"
Those expressions were popular around 1930, right?
You know, I went to elementary school in Queens NY, during the early 7O's, and you could certainly still hear those expressions being used. I always thought that perhaps because some of the kids had older parents, that type of slang carried over.
I remember one of my favorite expressions of disbelief was "Oh, baloney...", which did not go over well when I moved to the Wash DC area for junior high school.
