Galley (Grose 1811 Dictionary)

Building the galley; a game formerly used at sea, in order to put a trick upon a landsman, or fresh-water sailor. It being agreed to play at that game, one sailor personates the builder, and another the merchant or contractor: the builder first begins by laying the keel, which consists of a number of men laid all along on their backs, one after another, that is, head to foot; he next puts in the ribs or knees, by making a number of men sit feet to feet, at right angles to, and on each side of, the keel: he now fixing on the person intended to be the object of the joke, observes he is a fierce-looking fellow, and fit for the lion; he accordingly places him at the head, his arms being held or locked in by the two persons next to him, representing the ribs. After several other dispositions, the builder delivers over the galley to the contractor as complete: but he, among other faults and objections, observes the lion is not gilt, on which the builder or one of his assistants, runs to the head, and dipping a mop in the excrement, thrusts it into the face of the lion.
