A repetitive task usually involved in a Massively Multiplayer Online Role playing game (MMORPG) where a character's skill's are based entirely on killing monsters to gain strengths or levels. In most MMORPGs, there is no skill from the player involved, so anyone who plays 20 hours a day of grinding will be stronger than a player who does not. MMORPGs become a game genre filled with those who are too slow to play First-Person Shooters (FPS) or too dumb to play Real Time Strategy (RTS) but want to brag and be 1337 g4m3r so they play 20 hours a day and boast to "n00bs"

Grinding_Johnny210: You suck n00b!
