Screen Hunter 

One who commits the unethical act of looking off his opponent's screen during intense competitve video gamery between multiple players on the same television, to establish an unfair advantage for the cheater to rolfpwn his upstanding oponent, therefore lowering the overall true PWN4G3 factor. Thus compromising the integrity of the game.

I was sneaking up behind Dunsten with the energy sword while he was sniping someone on the other side of the map, when he suddenly stopped aiming to pull his shotgun out...hmm Dunsten is a screen hunter.
