Rectal prolapse normally describes a medical condition wherein the walls of the rectum protrude through the anus and hence become visible outside the body. There are three chief conditions which come under the title rectal prolapse:

Full-thickness rectal prolapse describes the entire rectum protruding through the anus
Mucosal prolapse describes only the rectal mucosa (not the entire wall) prolapsing
Internal intussusception wherein the rectum collapses but does not exit the rectum.
It is caused by weakness of the pelvic floor muscles and descending of the pelvic floor organs (uterus) - this is why the condition is most common among middle-aged to elderly women (women account for 85% of all reported conditions*). It is often accounted to chronic abdominal straining (notable in pregnancy, constipation) and anal sex.

The slang terms pink sock , or Ass Tulip is used to refer to when the rectum is pulled out during anal sex due to a variety of factors including insufficient lubrication and a much larger than average diameter penis.

Additionally, infection with whipworm can weaken these muscles and cause rectal prolapse in children.
