When one is completely, totally honest in their opinion when asked for it. Often these opinions aren't sugar-coated
like that of the regular "honest" person.
Mary: Chole, do you think Johnny and I are ready for marriage?
Chloe: You've only known each other for three months. You'd be marrying what most people consider acquaintances. Take your time.
Mary: You're such a bitch Chloe, why did I even ask? You don't always have to use brutal honesty!
Fred: (wearing old, tattered shoes) Do you think I should get new shoes?
Bill: Yeah, those are getting pretty out of shape Fred.
