A marine, former marine,a person with a relative in the U.S.M.C, or marine wanna be who takes pride in the U.S.M.C. to the point of absurdity.Jarheadtard are snobbish towards other branches(especially the army) and often talk trash about other branches.They are elitist and literally believe that the U.S.M.C is the absolute bestest military force in the world Eva.

A typical Jarheadtard looks down on the other branches, often calling them pussies(especially the army) despite never having served in the military nor does he or she intend to surve after graduation.
