A term given to gamers who die a lot in battle. Such as a mallard flying by just waiting to be shot. Someone who runs out in the open and is shot immediately.
Specifically in Halo 3 if the person dies 13 times in a 4 on 4 battle up to a 50, they are a mallard. 17 or more and you are an Uber-Mallard. It is usually required that you profess your malardry to the other teammates.

Eg., Teammate: "14 deaths are you kidding me? Say it." Mallard: "I'm a mallard.." Teammate: "Yes you are"
