Where does buff come from?

The gaming uses of buff appear to be extensions of the existing verb buff meaning “to polish or shine” (representing improvement) as well as the adjective buff (or buffed) meaning “having a physique enhanced by bodybuilding exercises” (representing enhanced strength). These and other uses of buff trace back to the Old Italian word bufalo, meaning “wild ox.”

How is buff used?

The verb use of buff is the antonym of the gaming sense of nerf meaning “to reduce the effectiveness of (something, such as a character, attribute, or weapon) in a video game.”

There is also debuff (both noun and verb), used for actions and items, etc., that negate buffs.
