Does anyone know what the etymology of buff/debuff is? Something to do with shiny naked muscles?
I imagine it's probably just an Americanism that evolved from someone making a mistake in definition or grammar, but where everyone knew what he meant, so there was a sub-collective agreement to just stick with his simplified gibberish for the sake of annoying the English.
As for what they mean in this game and others, to Buff (presumably a verb) is to enhance someone; to debuff is both, to strip someone of 'buffs' (now for some reason a noun), and to cast negative status effects.
