International Ragnarok Online, with a large majority of users coming from North Americe. There are four servers: Chaos and Loki, which are the two biggest, Iris, which is smaller and generally newer, and Sakray, the test server with 2x exp and drops. Some people like to complain about the bots and lag, but for the most part, they are probably little 12-year-old boys that jerk off to doujinshi.
Player 1: omg, fuck iRO, tihs lag is sooo fcking bad... omg, their r sooo many bot on this map... omg, teh GMs suck, they dont do shit...

Player 2: Dude, shut the fuck up. The lag is nowhere near as bad as in pRO or kRO, there are bots in every MMORPG, and the GMs are very professional and spell better than your trailer trash mom.

Player 1: OMGWTF???

International Ragnarok = LAG. The official Ragnarok Online Server, nobody where you are, you will always get lag. And dont even mind entering a town, its horrible!

Derived from the epitomy of sorrow that is International Ragnarok.

A Ragnarok Online server. Lag depends on your connections, and of course, to reduce it lower your image quality.
Horribly known because of the many bots there are. Although if they are not bots they are actually very nice.
I rather stay in a private server than in iRO... But of course... I got friends in iRO...

The pirate alphabet. It's made of 3 letters.

"I' or "aye!" - means hello, greetings, good day.
"R" or "arrrrrrrrr" - means planning something evil, or just frustration
"O" or "ooooh!" - means I just got pwned.
