look up any word, like fleek:
 
1.
Completely useless teammate in online multiplayer shooters, speciailizing in Resistance and Call of Duty. A lambchopper will always finish with 0 kills, double digit deaths, and EVERY NOW AND THEN get an assist or capture an objecitve in Domination.
Player 1 "Geez we got housed in that game, wtf happened?"

Player 2 sees scoreboard where teammate goes 0-13

Player 2 - "We got a Lambchopper"
