look up any word, like spook:
The act of blaming every negative thing occurring in modern video games on the use of mods, modded controllers, hacking, boosting, lagging, and other related activities, even when game play is totally fair. Can be very contagious.

Jake: No he wasn't, he just has skill.

John: I saw his mod, don't even try that.

Jake: So when did you contract grishosis?
