Where Did This Slang Come From?
Navy slang has one of the longest histories of any English slang category. Many expressions originated during the Age of Sail, when crews spent months at sea and created their own vocabulary to describe daily life.
Over time, technological advances introduced new terms related to engines, submarines, aircraft carriers, and modern warfare. Different navies—including those of the United States, United Kingdom, Australia, and Canada—developed their own regional expressions while sharing many common traditions.
The internet has given navy slang a second life. Veterans share stories on Reddit, military creators explain terminology on TikTok, and gaming communities featuring naval combat have introduced these expressions to younger audiences.
