Ha ha! That parody-song is so great!
Anyway, my characters are all based in Victorian England, so they can get away with saying things like 'popinjay'.
I'm so used to using words people would think were obscure or big vocabulary. The other day I was talking to my mom and she was like 'What type of word is that? I've never heard that.' In her defense it was kind of an old word, as in not used much in conversation nowadays, though I don't remember what word it was exactly.
P.S. I ran out of music to listen to, so now I'm writing to Christmas music X3 It's quite relaxing actually.
