NOUN. A nick name for marines. Originated from the "high and tight" haircuts that make their heads look like jars.

The derrogatory version means That your head is like an empty jar, thus meaning stupid.

Marines call each other jarheads, so it's okay to say it if your a marine or a friend of a marine.
Kind of like the word "nigga." niggas can say it, YOU CAN'T.
1.(marine)Once a jarhead,always a jarhead.

2.(derrogatory) Your about as confused as a jarhead fuckin' a football.

3.(nigga) Wassup, my jarhead?

Jarhead is a derogative term for US Marines based on the popular/common perception that they only follow orders and are incapable of individual thought as it is trained out of them in USMC basic.
Jarheads don't have to think. They only have to follow orders.
