A "glitch" refers to a temporary malfunction or irregularity in a system, often seen in technology and electronics. It can manifest as unexpected behavior, such as software errors, visual distortions in video games, or hardware failures. Glitches can occur due to coding mistakes, hardware limitations, or external factors like power surges. In the context of video games, glitches can sometimes lead to unintended gameplay experiences, such as characters moving through walls or performing actions not originally designed by the developers. While some players find glitches amusing, they can also disrupt the intended experience of the game, leading to frustration or confusion.
