"Pink Sock" — What It Actually Means

If you've come across the term "pink sock" and are wondering whether it's some STD you haven't heard of, the short answer is no — it isn't an STD at all. It's slang for rectal prolapse, a distinct medical condition.

What rectal prolapse actually is

Rectal prolapse happens when the lining of the rectum protrudes through the anus, which is where the "pink sock" description comes from — the appearance can resemble a rolled-up pink sock. It's caused by weakening of the muscles and connective tissue that normally hold the rectum in place, and it's more common than the slang term might suggest, particularly in older adults and people with a history of chronic constipation or straining during bowel movements.

Where the STD confusion comes from

Rectal prolapse isn't caused by, and doesn't transmit, any STD. The confusion likely comes from the fact that some STDs can cause symptoms — chronic diarrhea from certain bacterial infections, for instance — that involve straining during bowel movements, which is a genuine risk factor for prolapse over time. Anal intercourse can also contribute to prolapse risk in some cases, which is probably where the term picked up a sexual-health association despite not actually being sexually transmitted itself.

When to see a doctor

Difficulty passing stool, a feeling of incomplete bowel movements, or any visible protrusion through the anus should prompt a doctor's visit. Mild cases are often managed with dietary changes and stool softeners; more significant prolapse can require surgical repair.
