The slang dictionary - for new players:

Dictionary? Looking that up in the dictionary, I'd say this was more of an alphabetical list...:)

WARNING: This post may contain some strong language.

I am going to keep track of slang (post if I've forgotten any, or you want to make a contribution). This includes in-game slang like Org (Orgrimmar) etc.
