Glitch

A glitch is like when your computer or phone does something unexpected or weird - like when your game freezes or your picture gets all fuzzy. Sometimes it happens because there's a mistake in the way the computer code was written, or because there's too much stuff going on at once. It's kind of like when you try to carry too many toys at once and you drop some - things start to get mixed up and messy. People who make computers try really hard to make sure there aren't any glitches, but sometimes they still happen.
