Glitching

'Glitching is the controversial practice of finding and exploiting flaws in modern video games to achieve something that was not intended by the game designers. Gamers who engage in this practice are known as glitchers (or cheaters, depending on whether or not you agree with glitching.) While the term is mainly a neologism it derives from the German glitschig, meaning 'slippery.' Glitchers can be found on console video games as well as computer games. With the advent of high speed multiplayer gaming in the form of services such as Xbox Live and Playstation Online, glitching has grown in popularity. Despite this gain in popularity, glitching is still considered a subculture of gaming and has retained a negative image in the eyes of many gamers.'
