Fake Best Friend: some one who you don't really like and they don't really like you, but for some reason you both pretend to be friends; usually, to use each other for something!
Why were you hanging out with so-in-so today?
Oh! She's my FBF! We are the only two girls in that class, so we pretend to be friends for an hour.
