Screen cheater

A person who, typically in first person shooters (fps), will look upon someone else's screen. Generally frowned upon, looked-down upon, and it pisses people off.

There are a couple reasons for doing this. It will locate a person for you, and you will know which way to aim. You can see whether or not someone is following you stealth-like, usually only when radars are off. You know which way the bullets are coming from.

Not recommended.

Screen cheaters on Halo 2 pisses people off. It's a low way to get some points.

cheatery

(video games) So cheap it should be considered cheating. Typically describes a technique in a fighting game that instantly or flawlessly defeats the opponent, or a move that has no flaws and deals insane damage.
Derived from Super Smash Brothers (N64), whose fighter "Link" has the most powerful arsenal of extremely cheap attacks ever seen in a fighting game.
Originally coined by R. Sosa ("Twinkin' Out With Red Mage")

Way to hit me with the most cheatery move in the game, Link!
