Originated from an Assetto Corsa modder who kept doing it to the point of him getting bullied.

Its an overall term for stealing other people's Assetto Corsa mods and claiming them as your own, while not giving the original creator credit and making them worse physically and visually.
Person 1: "Yo, I got an EVO 5 model from a modder that I know, but its complete garbage, and it turns like a truck."
Person 2: "Ah damn, looks like that person was shrumming it !"
Person 1: "Right, lets rather not put it into our modpack."
