Factinista
A factinista is a person who acts like they're king of the world because they read a book. They don't care if you're right.
A factinista told me, 'You're wrong. The book says so.' I said, 'The book is wrong.'
My teacher is a factinista. She made me read a book for a week just because I said apples are better than oranges.
I asked a factinista why clouds float. She said, 'Because the book says so.'
