WoW, actually...

When playing an MMORPG and players try to explain a concept that you're very familiar with in general chat when you didn't ask. Usually the "advice" is unrelated to the question, if any, that you asked.

Druid: Hey, is anyone an Engineer? I need an item and I don't really want to waste time running back to town.

Mage: There's an Auction house in Orgrimmar, why don't you just buy the item there?

Druid: But the whole point is that I don't want to run back and waste time.

Mage: You should set your hearthstone for Thunder Bluff, it has all the same stuff as Orgrimmar and it's centrally located on the continent. You can easily get anywhere and it's cheap to fly to other capitals.
Druid: Are you an engineer or not?
Mage: No, I'm a Tailor/Enchanter
Druid: Oh FFS... did you just WoW, actually... me?
