WAG, n. [from the verb.]

A droll; a man full of low sport and humor; a ludicrous fellow. We wink at wags, when they offend. – Dryden. The counselor never pleaded without a piece of packthread in his hand, which he used to twist about his finger all the while he was speaking; the wags used to call it the thread of his discourse. – Addison.
