Master Chiefing It

Attempting to be a one man army.

A bad-ass soldier from the video game "Halo: Combat Evolved". Usually seen in green MJOLNIR Mark-V Armor. Synonymous with 1337.

The protagonist from the Halo Series by Bungie. He could totally kick you ass. And you know it.

Master Chief is the name of the rank that John is, his spartan number is 117. He is the playable character in both Halo: Combat Evolved and Halo 2. Hes a badass character, hes so badass that he just has to walk on screen and you can feel the badassness radiating from his badass aura of badassness. He doesn't need to walk on screen and snap some necks or crack some skulls to look like a badass, he just walks on screen. Okay, enough of my undying love for the most badass video game character.

If you're playing Xbox Live, and you just so happen to come across someone with the name "Master Chief," you've been blessed.
Now, there are plenty of people that go under that name and then add excrutiatingly long numbers, but if you see the original "Master Chief," consider yourself a child of good luck.

When your playing a game where you can just go up to the enemy with your guns blazing and end up taking them all out and not dying.

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.
