pixel sort

n. [Commodore users] Any compression routine which irretrievably loses
valuable data in the process of crunch ing it. Disparagingly used for lossy
methods such as JPEG. The theory, of course, is that these methods are only
used on photographic images in which minor loss-of-data is not visible to
the human eye. The term pixel sort implies distrust of this theory. Compare
bogo-sort.
