purple sock
The common name for a medical condition in which the rectum becomes inverted and is extruded through the anus. This is a very painful condition which is generally the result of vigorous anal sex. It is called a "purple sock" because that is the best description for how the inverted rectum looks. (see also ass tulip)
Dr. Smith suspected his wife was seeing another man when she started coming home at 4 AM, suddenly had an intense anal fetish, and showed up in his ER one night with a purple sock. It ended up the "other man" was in fact a horse.
