Gedunk refers to ice cream, candy, potato chips, and other snack foods, as well as to the place on a ship where these items are sold. The first known published usage of the term "gedunk" in a non-naval context is in a 1927 comic strip which refers to "gedunk [ice cream] sundaes." In 1931 it was mentioned in Leatherneck magazine; subsequent early naval usage includes Robert Joseph Casey'sTorpedo Junction: With the Pacific Fleet from Pearl Harbor to Midway (published in 1943); and Robert Olds' Helldiver Squadron: The Story of Carrier Bombing Squadron 17 with Task Force 58 (published in 1944).
Usage of the pejorative term "gedunk sailor" to refer to an inexperience sailor apparently dates to 1941, and is mentioned in Theodore C. Mason's Battleship Sailor, published in 1982.
The origin of the word gedunk is uncertain, though it has been suggested it derives from a Chinese word referring to a place of idleness, or a German word meaning to dunk bread in gravy or coffee.
Ice-maker and refrigerated compartments were first introduced on some U.S. Navy ships in 1893, and an ice-cream maker is reported on board USS Missouri (Battleship No. 11, later BB-11) as early as 1906.
