in World of Warcaft, a funny way for Horde players to annoy scare Alliance players.
Because of the language mess-up system in WoW, if a Horde player says "UO UO", any Alliance player who hears it will see "HA HA" instead. most of Allys run away seeing that, thinking they've met a GM's alt who has cross-faction communication. "UO UO" can be extended, so if you prefer "HA HA HA" over "HA HA", there's no problem!

try it out!
Horde player: *kills an alliance player* UO UO

Other alliance player to alliance player: omg this guy can write to us normally O.o i better run away hes a gm or something cya *bubble hearth*

Short for Ultima Online, a game released in late 1997. This was the "first" successful MMORPG (Yes technically there were others but none on the scale of UO). It was possibly one of the most unique and immersive games in the market at its peak (98-01). The game was quickly massacred and mutilated beyond recognition with nerfs/cheesy neon graphics after the release of its third expansion.
I used to play UO for the PvP... now I'm waiting for WoW

Short for Ultima Online. It is overall a very interesting game that has been around for five, nearing six, years. In essence, it is a drug.
