Factinista
Factinista is a name for people who act like they're the smartest person in the room just because they read a few pages.
At lunch, a factinista told me, 'You're wrong. The book says so.' I said, 'The book is wrong.'
My mom is a factinista. She won't let me watch TV unless I read a book first.
I asked a factinista why the sky is blue. She said, 'Because the book says so.'
