Buff
Etymology
From "buff" in the sense of polishing or building up (as in "buffed up"). It arose in online gaming communities alongside its antonym nerf, describing patch changes that increase power.
verb · /BUF/
To strengthen or improve a character, weapon, or ability — the opposite of a nerf.
What it names
It names a deliberate upgrade in a game’s balance, and now any move that makes something stronger or more capable. It’s the counterweight to nerf in the endless tuning of systems.
Example
They buffed the underused classes, so the roster finally feels balanced.
Related idea
The direct opposite of nerf (a deliberate weakening); a buff dials power up, a nerf dials it down.
noun · /BUF/
An enthusiast and self-taught expert on a particular subject — a “film buff,” a “history buff.”
What it names
It names devoted amateur expertise: deep knowledge pursued for love rather than profession, the person who has read everything on their pet subject.
Example
She’s a serious opera buff — she can date a recording from a few bars.
Related idea
Warmer than a connoisseur, which implies refined authority; a buff is an ardent hobbyist, expert by sheer enthusiasm.
