nerf

Nerf is an anagram for non-expandable recreational foam, used in things like stress toys and as projectiles of some toy guns, great for firing at people around the office, although I would recommend that you work in a relaxed working environment first, as a stray foam projectile in your bosses coffe could lead to your dismissal.

This can also be used to describe a shot in a game that caused little harm (as with the foam projectiles).

Player 1: Yay! Direct hit! That must've hurt!
Player 2: Nah, you just nerfed me.
