I found a training thing that included the phrase "retard power" in an aviation context. The best part was the way it was enunciated. Not "ri-tard" like you do when it's a verb, but long E ree-tard. I absolutely clipped it.

That's hilarious. Is it still in use or say it differently now?

I'm thinking about master>slave in tech. Or rapeseed became Canola. Or how we say Uranus differently.

Printers used to refer to the page separation rollers as retard rollers.
