look up any word, like ethered:
Akronym of Wrath of the Lich-King, the upcoming expansion for the very popular MMORPG World of Warcraft.

"Wolk" can aslo be used as an alternative as a short for Wrath of the Lich-King.

-Omg, they say that a new class will be able to play with Wotlk! Death Knight! Nice!
-Yeah but you know they also say that you will unlock that class at lvl 80...
-Oh man, it will take me years to lvl to lvl 80... :(
