Why woman stick out tongue?

Answer 1

If a woman sticks her tongue out, it is probably an informal, almost flirty way of telling someone she might not approve of something you've done or said. But when little girls stick out their tongue to little boys, they usually mean it. They aren't doing it to flirt; they're doing it to get it through to a boy that they don't like him. But if a woman does it, chances are she's flirting with the man. HELLO,sometimes it is just a friendly gesture from the Sister.
