I had a contracting interview where I used the expression "to come on like gangbusters." As soon as I said it, I realized that to those not of a certain age, that expression is probably strange and puzzling. Luckily, the fellow interviewing me was not extremely young or maybe heard it before and let it pass.
I was thinking about terms and expressions, like dialing a phone or telegraphing one's intentions. The newspaper I delivered as a boy had a columnist who liked to list "faded phrases" in his columns. Ever hear the expression "is it bigger than a breadbox?" I'm sure it would draw puzzling looks from many people because they don't seem to be used nowadays. After that thought, I noticed an article at bread.com (I wanted to see what was there, but it's only a large regional bread company).
While there, I saw that they recommend storing bread at room temperature rather than in the refrigerator, where they say it goes stale quicker. So I guess there is some value to the old antiquated breadbox.
As I said, I used to store bread in the refrigerator. If I would've said I stored it in the icebox, you might have also had an inkling I'm on the early side of the baby boomers.
At one time, icebox was a synonym for refrigerator, harkening back to when blocks of ice, delivered regularly, kept foods chilled.
