I had heard a while back you guys were looking for MMO memes and I know of a good WoW related one. I am not sure if it’s prevalent outside WoW at all.
Original flash+video, I do not know the date of origin for the flash or the original audio. General info: the guild is called Wipeclub and it raided during “vanilla” wow. It had a very funny sounding GM named Dives who yelled at people for sucking during raids a lot, some other videos of his tirades exist.

Apparently it originated early 2006.
Blizzard later made references to the video in achievments for the level 80 version of Onyxia’s Lair (Remade for WoW’s 5th anniversary):
And of course there are ten man versions as well.
