A Warthog that has been improved to a state of win. It must be completely loaded to its max capacity of 3, a driver who achieves multiple splatters, a gunner who does not lose one on one and a passenger using a weapon that requires aim, and possible scoping.
Michael: I just splattered someone.
James: And I lasered that hog.
Michael: Well this is clearly a winhog with Matt killing everyone else.
