"Don't you dare" is an expression used to convey a strong warning or threat. It is often used when someone is about to do something that the speaker believes is wrong, foolish, or inappropriate. The phrase is meant to stop the person from taking the action and may imply that there will be serious consequences if the action is taken. It is a more forceful and emphatic way of saying "don't" or "you must not."
