I was thinking about the phrase ‘The pot calling the kettle black’. It comes from a time where cooking was done over open fires and cookware would become visibly ashy. (Fun fact: It first appears and was perhaps coined by Cervantes in Don Quixote!)
What are some other idioms that have lost their literal connection to time? What would be a good modern replacement?
To update replace all with car.
Dont look under the hood of a gift car.
Buckle up.
Hold your engine.
Get out of your limousine.
Turn the key on a drowned engine.
You could still use Hold your horses because the car has horse power. Pressing the brake pedal literally holds your horses.
But that in itself is an outdated idiom. A car has engine power.
