A sail warship carrying guns on three fully armed decks. Usually additional guns were carried on the upper works (forecastle and quarterdeck), but this was not a continuous battery, so these did not count. Three-deckers were usually ships of the line, classed as first-rate or second-rate.
OR: You can go with a sandwich made of three slices of usually toasted bread, but you're likely to lose the war.
