In
video games, a glitch is a programming error which results in behavior not intended by the programmers. Glitches may include incorrectly displayed graphics, collision detection errors, game-freezing or crashes, sound issues, and others. Some glitches are potentially dangerous to the game save data.

"
Glitching" is the practice of a player exploiting faults in a video game's programming to achieve tasks normally impossible if the game's script runs as intended (Such as running through walls or defying gravity).
During
quality assurance (such as the role of a
game tester for
video games), glitches must be located, a report compiled, and then fed back to the programmers.

Though commonly used by game players and the general public, the term "glitch" is rarely used by game developers, publishers, and QA departments. Instead, the more common term of software bug, or simply "bug", is used by professionals working in the video game industry.
