look up any word, like bukkake:
Someone who plays an objective-based game mode in a shooter video game for the sole purpose of getting a high kill count to pad one's stats while completely ignoring the objective. Heavily frowned upon and borderline cheating. Kill farmers are not legit.
Dude, that douchebag is a kill farmer. His K/D is 48/7, but he has no checkpoint captures at all.
