Today, the word can be used of any minor malfunction or snag. If you’re a gamer you might even take advantage of a glitch that causes something unexpected, and sometimes beneficial, to happen in the game.
A glitch is a brief technical fault, such as a transient one that corrects itself, making it difficult to troubleshoot. The term is particularly common in the computing and electronics industries, in circuit bending, as well as among players of video games, although any purposely organized structure, such as speech, may experience glitches.
