The most badass videogame character. Ever. Commenly seen with a MA5B 7.62mm Assault Rifle and using it to blow the hell outta Covanent aliens. Wears a uber-pimp set of green armor. Never see his face.
Master chief will blow the hell outta those dumb bugs, untill he has nothing left to shoot them with. Then, he will strangle them with their own living guts. -Sgt Johnson on Legendary

The Master Chief is done when the man is multitasking and having doggie style sex with his significant other, while playing halo 3. The man then proceeds to stick the controller handles into the ass and vagina cavities at the same time. Be sure to keep the buttons out so that you can finish the fight.

I got a killtacular while giving my girl the Master Chief last night!
My girl got doo-doo on my controller when I gave her the Master Chief.

1)A very quiet character who single-handedly committed ridiculous genocide to an intelligent alien race, while never saying more than a few words.
2)Your typical mass murderer.

Short for Master Chief Petty Officer. The Master Chief Petty Officer is the ninth, and highest, enlisted rank in the U.S. Navy, just above Senior Chief Petty Officer, and is a non-commissioned officer. They are referred to as Master Chief in most circumstances.
Advancement to Master Chief Petty Officer is similar to that of Chief Petty Officer and Senior Chief Petty Officer. It carries requirements of time in service, superior evaluation scores, specialty examinations, and peer review. A Senior Chief Petty Officer can only advance if the existing master chiefs approve.
A Master Chief Petty Officer is purely administrative and is usually tied closely with the Commanding Officer, except possibly when the command is very large (e.g. an aircraft carrier). Their uniform reflects this administrative duty; becoming similar to that of an officer, albeit with different insignia than an officer.

The main character from the Xbox and PC game Halo. As a boy, named John, he was captured along with several other children by an organizations who's goal is to train kids to be super soldiers by their late teens. John, along with 20 some other "Spartans" passed the training and have fought some of the most amazing battles known to man.
The Master Chief walked into the bar and sat down. Then he pulled out a deagle and shot everyone in the head.
