Most of us have heard the expression "....put his lights out!" I'd always assumed it dirived from the act of blowing out a candle or turning off an electric light.
Then quite awhile ago I read something about eating "lights". Found out that "lights" use to refer to lungs and people actually ate, maybe still do, them. I believe the orginal expression was, ".... let his lights out!" meaning that some one had been shot or stabbed through the lungs. Can any of you confirm or refute this?
Another expression I use to be confused about was "Lock, Stock, and Barrel" Before I realized it referred to the lock, stock and barrel of a gun I thought it derived from a merchant selling his business including, the lock to the door, the stock of goods and even the rain barrel.
Can you come up with other expressions that have evolved over the years that may have a different meaning now than when they were orginated?
