And it's been around even longer than that, though i can't remember the first time I heard it... probab on a MU* someplace. I know the earliest MMOG usage I heard was probably in Subspace way back in the dawn of massive multiplayer, but it wasn't new then, either.
All you need to know is it originates with Nerf a long time ago, and refers to something in a game(usually something considered overpowered, but not exclusively), being made less-powerful-- IE: Less dangerous, like a Nerf ball.
Nerfs do exist in Star wars, but that's not where the term originates and has nothing to do with the gaming slang.
AND NOW YOU KNOWWWWW the REST of the backstory... GOOD DAY!
