Folks who "ain't used to nothing" usually perform outlandishly when they get it. It could be anything from wasting winnings from the lottery on trifles, or as mundane as hollering at a minor relative's graduation from high school, junior high school, even from preschool. They must clown and act up to be seen, heard, felt, and/or "envied!" Sadly, they do not know or suspect that their behavior is crass!
