Upon having anal sex with a person, the catcher or the person taking the anal sex tightens their rectum as the person giving pulls out, causing the rectum to pull out of the anus. That is a dirty sock.
Dirty sock - Gayest thing that can happen unless its with a women and it's still pretty disgusting, because why would you have anal sex if god gave women pussies to fuck, just fucking nasty.
