European Extreme 

A difficulty level that first appeared on the European release of Metal Gear Solid 2: Sons of liberty, which was released several months after the other versions.

Basically, it's a step-up from the previous hardest difficulty, and reserved for hard-core gamers and/or people with too much time on their hands.

A: I finally did it! I cleared MGS2 on European Extreme!
B: A month well spent.

European Extreme 

adj. The state of something being so radical and potentially dangerous that it exceeds the rest of the world's standards of "extremeness." The modifier, "European" refers to the higher, snobbier, level of sophistication which comes with the existing extreemeness. The phrase was coined by the video game Metal Gear Solid 3: Subsistence, where the European Extreme mode was an additional difficulty level unavailable in the United States on the release of the first version of Metal Gear Solid 3.

Person A: Damn, that guy looks like he's built out of marble and carved by Michelangelo himself, he must workout like a fiend!
Person B: You don't know the half of it, he runs 20 miles in the morning, lifts for 3 hours in the afternoon, and runs another 20 miles in the evening. He does this even in the dead of winter.
Person A: Shit, that routine is European Extreme man.
