Pink sock is the colloquial term for rectal prolapse caused by vigorous anal penetration. It is named thus because the distended, exposed anorectal tissue resembles a crumpled up pink sock. It is sometimes also called “meat sock” and “rosebudding.”
A rectal prolapse is a serious medical condition that can be cause by a number of circumstances. The complete explanation of the condition is that a part of rectum, the large intestine’s lowest section, “falls” or slips outside of the anus. It occurs when the tissues and ligaments that hold the rectum in place and support it are weakened or damaged. Rectal prolapse can develop into a chronic condition.
For most of our lives, that strong, muscular sphincter at the end of the digestive track does a good job ensuring the rectum stays in place. While some rectal prolapses can be fixed by simply pushing the rectum back through the anus, all occurrences should .
In relation to sex, a pink sock can be caused by anal penetration that is both rough and not accompanied by enough lubrication. Because the anus and rectum are not self-lubricating, some form of lube is highly recommended for anal play. If sufficient lubrication is not used—before and during anal penetration—the rectal cavity may begin to dry out. This can cause ripping and tearing of rectal membranes and possibly the anus. As the cavity becomes more dry, the membranes may “stick” to the penis, fingers or sex toy involved and the rectum could follow the penis when it exits.
Despite rectal prolapse being a dangerous condition, some folks fetishize and encourage their own or others pink sock to occur. After the rectum is exposed, some folks enjoy performing or receiving different types of touch to the pink sock, including touch, licking, fingering or even attempting further penetration.
