Glitch

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. A glitch, which is subtle and often temporary, differs from a more serious bug, which is a genuine breakdown in function. Videogame writer Alex Pieschel says that although the two words are often used interchangeably when describing software, the more "blameworthy pejorative" of bug indicates something that can be reliably diagnosed and corrected, while glitch describes a situation "more transient, abnormal, illogical, impermanent, or unreliable", caused by unexpected inputs or something outside of the code.
