I'm pretty surprised this isn't an article already. It's mentioned in the Dark Souls article but it totally deserves its own in my opinion. It's one of the biggest memes in the Dark Souls fandom along with Praise the Sun. It's really associated with the word "casul" and the phrase "what r u casul" as well as other ironic stuff about the hardcore gaming crowd. If you don't know who giantdad is, this is all you need to understand.
So, anyone up for writing it?
