He thought it came from Pokemon XD. I had to be blunt. Seriously, that was too far. xD I mean, all of us come to times when we don't know what something means, but he actually attributed it to a Pokemon game. A smilie which is used everywhere across the internet, coming from a Pokemon game. XD
might be from pokemon Xd? gale of darkness?

(I think I'll apologise to him, though. I was being a bit of an attention-seeker there, :[ )
