Just an average, casual conversation between people in the U.S. Navy would likely make no sense to outsiders. Though some terms have seeped into the mainstream due to movies or other pop culture references, some are still quite baffling. If it's "taps," that means it is lights out and time for "rack," which means bed. If you're in the "galley" (kitchen), you may be heading over to the "scullery," which is a place to wash dishes. And if there is a Naval officer who is considered a sort of jack-of-all-trades, he is known as a boatwain's mate.
