What does, if anything, Azeroth mean?

Now before all you wow junkies get on your high horses read the whole question. IK azeroth is the name for the world in wow. the question arises from this. I was Watching an old show Called MEGAS XLR in season one episode 12 Coop D'Etat the hilariously parody transformer king calls the thing "the Sacred Undying Flame of Azeroth." So what does Azeroth mean in this context and/or any context.
