American slang for a US Marine, and one of the most enduring military nicknames in the language. The term dates back to the leather stock collar Marines once wore around their necks — either to enforce upright posture or protect against sword slashes, depending on who you ask. Today 'leatherneck' is worn as a badge of pride by Marines themselves.

My uncle was a leatherneck for twenty years — he never really stopped being one.
Origin: From the leather neckband that was part of the US Marine uniform in the 18th and 19th centuries. Editorial expansion authored on Slangora.
