act your age. Perhaps act your age! originated as a reproof to children, but it is directed at both children and adults today, meaning either don’t act more immature than you are, or don’t try to keep up with the younger generation. The expression originated in the U.S., probably during the late 19th century, as did the synonymous be your age!
