jarhead

A member of the United States Marine Corps. When used by civilians it could be considered derogatory, but it is used often among Marines.

The term originates from the "high and tight" haircut that many Marines have, which makes their head look like a jar. It did NOT originate from their uniform or cover.

A term used to describe a US Marine. Although some believe the term is of recent origin (Gulf War), it has been around for a long time (at least since World War II). It has nothing to do with haircuts, hats or headshape. It refers to the Marines propensity to follow orders, regardless of consequences or personal safety. Because of their single-minded willingness to put their duty before themselves, Marines are said to have jarheads...hard on the outside and empty on the inside. It is a good thing there are such men.

jar-head (n) a member of the United States Marine Corps..... OOooraaAAHH!!

A word used by both ordinary people and marines to talk about marines. The term jarhead came out because of the very short hair cuts which resembles that of a jar.

The term "jarhead" comes from the shape of the Old Corps covers (hats) that were worn by Marines. The poster is assuming that it is derrogatory, but in fact Marines call each other jarhead as a matter of course.
