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.
There’s the -dooj suffix, which means “a familiar thing that should be around here somewhere, and that has such-and-so quality.” This is useful for asking questions like “Where’s the … the clickydooj?”
(The variant spelling -doodge is also acceptable.)
I’m not seeing anything related to this do you have a source somewhere I can read up about it? I’ve always used “doohickey” in this way and I’m wondering if it’s related
