The answer was essentially:
"In this 2004 role-playing game, players return to the world of Azeroth, where heros like Leeroy Jenkins do battle."
They actually mentioned Leeroy, a completely unofficial part of the game. I caught it on TV and proceeded to laugh my ass off. Made my day. Although I am also reminded that you can't look him up on Wikkipedia (other than a vague, POV-filled half-paragraph in the World of Warcraft article). So screw those elitist twits who think they know what's prevalent/important information and what isn't; all I ever see is them debate what subjects do and don't belong there, I've even seen them discuss deleteing entries for ancient mythological beasts. They're just unintellectual people who are bitter they can't be real scholars or archivists. But I digress, I'm still amused to have heard Leeroy Jenkins be a Jeopardy! question.
*Giggle* Leeroy Jenkins...
