Frontier justice is to take justice in to your own hands regardless of the possible legal ramifications it may entail.

Punishment or payback rendered at the hands of a vigilante or any other punishments given outside of official channels. Often times the punishment is illegal and excessive for the violation.

Something that can be acheived by taking off every zig.
Only to be attempted if you know what you doing (ie. move zig)

A reference to the class in Team Fortress 2, Justice Engineer is considered the 10th class.
The Justice Engineer is, quite obviously, a badass. The only difference between him and the normal engineer is that the Justice Engineer's default hat is the Texas Ten Gallon, and prominently uses the Shotgun. He automatically critical-hits any evildoer.
Justice Engineer can strike at any time, and is always watching.
Always.
Justice never sleeps.

Olive Justice=perfection. She makes bed really nice, LOLJK we mess them up. She likes olive, and Jews, and gingers. She likes to act ghetto in her van by herself while smoking some weed. She likes to drink Four Loko mixed with vodka. She kind of wishes she was Jewish. She is cool, yanno? oandshortandcoot. <3 BUT TOTES.

One of the only good shows currently on Cartoon Network (other than Batman: The Brave and the Bold) amidst the multitude of shitty shows like The Adventures of Gumball and whatnot. Features teenaged heroes who are part of a covert team that work for the Justice League. Pretty badass in that it contains kick ass animation and fight sequences along with comedy and some drama.

A Halo Machinima series made by Jon CJG, the same person who made Arby 'n' the Chief. It revolves around a good cop in a totalitarian city trying to turn the force around. It is known for tag-lines such as "Jesus Christ, Howard' and the famous Indian in the Cupboard scene.
The name is derived from the name of the special forces, the Eradication of Repulsive Evil and Corruption Team, or ERECT. Geddit? HARD justice? Haha.
