@AIQ I use that word sometimes. Some people say kerfluffle accidentally instead. I think the kerfluffle version sounds cute.

Oh yeah, it’s not that uncommon, but even native speakers are still acquiring the vocabulary of their languages over time, day by day, year by year, throughout their lives. We all learn things in our own ways and in a different order from other people, even though we tend to naturally think everyone else learns things at roughly the same time.
