big as life

Also, large as life. In person, as in And there was Mary, big as life, standing right in front of me. This phrase transfers the same size as in real life (life-size) to an actual appearance. Sometimes this term is embellished with and quite as natural, presumably alluding to a likeness of a person or thing that closely resembles the real thing. A similar addition is and twice as natural, which doesn't make sense. [Late 1800s]
