Oops. I said I knew how to spell it, not what it means. ('If you never misuse a word, you're spending too much time second-guessing yourself/reading the dictionary'?) For some reason I thought 'floccinaucinihilipilification' meant 'nitpicking'. Probably I inferred its meaning incorrectly from the context in which it appeared; that was my standard failure mode, during the era when I assume I picked up that word. (In fairness to my child-self, it was before widespread internet access--but not dictionaries.)

Also, I think I was suffering from some kind of localised cognitive impairment when I wrote that comment (sleep deprivation, perhaps). It strikes me as pretty boorish now, as well as incorrect.

No, but I am.
