pixel sort n.

[Commodore users] Any compression routine which irretrievably loses valuable data in the process of crunching 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.
