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.
Couldn’t think of “croissants” as a kid, called them “curly rolls,” my uncle mocked me as a true product of the south, etc…
