A reason why things such as: websites not dispaying correctly (wrong font size, PNG images not working correctly), web browser crashing, cookies not being saved, etcetera, usually occur. Can also be applied to nonsensical situations, see the chewbacca defense
Joe: This website is all messed up, the font size is too small, and the PNG images don't render correctly!
Jill: IBYUIE, Joe.
