Truth is

Robert Penn Warren speaks the word in All the Kings Men. 

"Her eyes were glittering like the eyes of a child when you give a nice surprise, and she laughed with a sudden throaty, tingling way. It is the way a woman laughs for happiness. They never laugh that way just when they are being polite or at a joke. A woman only laughs that way a few times in her life. A woman only laughs that way when something has touched her way down in the very quick of her being and the happiness just wells out as natural as breath and the first jonquils and mountain brooks. When a woman laughs that way it always does something to you. It does not matter what kind of a face she has got either. You hear that laugh and feel that you have grasped a clean and beautiful truth. You feel that way because that laugh is a revelation. It is a great impersonal sincerity. It is a spray of dewy blossom from the great central stalk of All Being, and the woman’s name and address hasn’t got a damn thing to do with it. Therefore, the laugh cannot be faked. If a woman could learn to fake it she would make Nell Gwyn and Pompadour look like a couple of Campfire Girls wearing bifocals and ground-gripper shoes with bands on their teeth. She could get all society by the ears. For any man really wants is to hear a woman laugh like that."
