Factinista
Factinista is a name for people who think they're the only ones who know the truth, and they'll prove it by making you read a book.
I asked a factinista why the ocean is salty. She said, 'Because the book says so.'
My neighbor is a factinista. She yelled at my dog for not knowing the answer to a math problem.
A factinista told me, 'You're not smart. Read the book.' I said, 'The book is wrong.'
