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!
