Definition: "If you are going to be punished for something, you might as well be punished for something big, as for something small."
Etymology: The origin of this idiom dates back to nineteenth-century England, when a person risked being deported or killed for stealing sheep, no matter what the age of the animal was. Therefore in this respect, the thief might as well steal a sheep (which has more meat on it than a lamb), as the punishment was just as severe if it was a lamb that was taken.
