Everybody is writing about 
'nerfing' this and 
'nerfing' that, but can anyone tell me what this really means? I mean, I know pretty well what it means by now, but where does the word 'nerf' itself come from?
A dictionary didnt help at all, and wikipedia referred to some sort of child-safe-foam-pLastic-toys, but that doesnt capture my imagination of a 
'nerfed vampire queen' (She's still ethereal and not pLastic, isnt she? And what's a child-safe vampire queen supposed to be good for at all? 

 ). I also thought about a forum search on 'nerf' to see who started it, but there are way too many hits on that word and no option to order the results by date...
