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.
My mom sometimes uses “doomaflagidad” for basically anything. The only way I’ve been able to translate is by using context clues. Usually based on what we’re talking about or if she’s pointing or using hand gestures.
