"Get lost" is a phrase that means to lose one's way or become lost. To get to the point that you don't know where you are. It's also a phrase that can be used in a rude way to tell someone to go away. Ex: Get lost, kid. You're annoying us. Ex: We got lost on the way here, so we stopped to ask for directions. Ex: Try not to get lost! The market place is quite big.
