I have, twice that I can remember.
- Nukamajig - microwave. I still use it from time to time because it’s too stupid not to.
- Miscombobulate - mixup and confuse. Just now, between the time it was and when the appartment building’s laundry room was closed for the night.
You people are way too bright with your apt and often witty alternatives for when you forget something’s actual name. Me? I just employ an entirely random sound or made up word. It drives my wife insane. “Babe, would you pass me the…fucking… spraaaal?”
