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.


Swedish is awesome with compound words, say that you forget the Swedish word for “computer”, “dator”, you could just use “informationshanteringsmaskin” instead!
I used three words to make one compound word, the words I used was:
“Information”, “hantering” and “maskin”
Informationhandlingmachine ?
Yeah!
