grinder

A player in massively-multiplayer online (MMO) games that is content to complete mindlessly repetitive tasks in order to increase an arbitrary number within a game to "level up".

Player A: "Hey, QuidditchKid792. How did you get your level up so fast from last night? You must have gone up three levels!"

Player B: "My friend is a grinder, and he leveled me up all last night in exchange for some Tier 6 equipment."

Some asshole who spends hours on end killing mobs in various MMORPGs with no real aim or purpose to gain levels at a supposedly increased rate.

Did you see that Grinder running around in Stranglethorn Vale? The guy should totally be doing the Green Hills of Stranglethorn quest while killing those humanoids.
