To 'pull a Jagex': To screw something up; fix things that aren't broken; dramatically change things for the worse.
Person 1: "Dude, they just changed the whole theme."
Person 2: "God, what Jagex's."

Person 1: "They just changed the entire format for no reason?"
Person 2: "They pulled a real Jagex. Bastards."

A Java company which has made games such as Runescape, Gold Miner, and others. Started off with Runescape Classic, went on to Runescape 2; currently known as Runescape. Jagex used to care greatly about the well-being of players, HOWEVER, now they say one thing when announcing updates, and doing the opposite! (See below examples)
Example 1:

Me (reading Behind the Scenes a preview of the month's updates, posted by Jagex.): Hmm, it says there will be a duel arena update here....new tournaments....alright, sounds good!

*A week later at the time of the system update*

Me (reading Behind the Scenes): Hmmm.... duel tournament....better interface system...Large prizes....limitation of staking....WHAT! LIMITATION OF STAKING!? I don't recall reading this....

*Goes to Behind the Scenes posting*

Me: No..I definately did not see this...they lied to me, what Jerks...

Example 2:

Me: (Reading Behind the Scenes, one month later): Hmmm, two new games to the wilderness....one is clan oriented...another is about hunting your target, alright...doesn't sound that bad..

*Two Weeks later...*

Me: *reading Wilderness Update*: Hmmm....let's see...Clan Wars...sounds good....Bounty Hunter.....eh, it's alright.....No PKing (Player-killing)...WHAT! NO PLAYER KILLING!? DID I READ THIS ONCE!?

*goes to Behind the Scenes post for that month.*

Me: Nope....apparently not, man, these guys are jerks, they could've at least told me!

A very underrated compary from 1999 to around 2007. Produced a hugely popular game with minimal cost. Unfortunately, they fell to the old addage: "Absolute power corrupts, absolutely."

In the final months of 2007 Jagex went on a power trip. They tried to control prices and got rid of the one truely great aspect of the game, PKing.

They claimed it was to "save the game", but, in the process ruined it for most everyone who played. eg. Ruinedscape
Person 1, June 2004: Yeah, I really liked Runescape, cheap and fun. PKing is great and easy to finace by Merchanting.

Person 1,January 2008: Well, Jagex went on a power trip and ruined their own creation. Killed merchanting as well as PKing. I have stopped playing, like thousands of others, in the wake.

noun: A highly successful company bent on taking over the world. Jagex' primary goal is to document the effects of a communist, totalitarian government on a large mass of people (an average of 100,000 playing RuneScape at any given time). Jagex takes pride in their famed censorship enforcement as well as their multitude of corrupt Player Moderators, simply made Player Moderators because they demonstrate how to follow the rules (and gave MMG head). Andrew Gower, founder of Jagex, is a highly accomplished Marxist Game Developer as well as the 363rd richest person in the United Kingdom. He is also famous for having a neck resembling that of an iguana.

verb: To Jagex means to fill one's day, facebook wall, or blog, or life with many pointless updates aimed to generate a highly negative response.

adjective: Something that is Jagex is something either related to internet trolling, the act of quiffing, or the gay porn industry.
A typical RuneScape coversation:
Mike - Hey dud* where can I find ****** *a****s*?
Peter - Yeah I ***** a **c** with **** yesterday ******t* lumbridge tutor **** with a ********* pot of ******** *** ***** fun.
Johnny - You have to be at least 13 to play RuneScape?!
Pmod - All banned for excessive use of offensive language. But if you apologize I might mute you to make the game even more pointless and piss you off. Viva Jagex and Lenin!
