It is the predecessor to the Pink Sock phenomena. When you are being anally annihilated, and your partner pulls out their dick or fingers, or whatever form of anal probe you decide to use, so fast that your intestines actually dingle from your ass. Not to be confused with dingleberries.

The only way to cure a brown sock, is for it to transform into a pink sock. One must turn around and tell their partner to clean their brown sock with their mouth until they are cured and have a nice pretty pink sock.
1: So I was getting ass fucked by Joey the other day and when he finished he pulled out so fast I got a brown sock.
2: Did he fix it for you?
1: Well I turned around furiously and said suck on my brown sock bitch. And he did. So now I have a pink sock like you.

2: I like pink socks, not brown socks.

This is an especially cruel prank to play on somebody. Though there are few documented instances of somebody performing a brown sock attack, it has happened. Party A defecates into a large sock, preferably a tube sock. After the sock is weighted down with the fecies inside, Party A ties a knot near the secrtion of the sock that is occupied by the fecies. At this point, Party A proceeds to spin the sock around (holding it by the clean side of course) and smacks Party B (who is most likely drunk and/or passed out) across the face.

Though this assault is rarely painful, the ego of Party B will be severely bruised by this most unsanitary of pranks.
Yeah so Bob was being a dick the other day so I decided to give him a brown sock. When he wasn't looking I loaded up one of his tube socks and cracked him across the face with it. Oh the hilarity that ensued.

The act of pulling your anal canal out of your anus; thus creating a "brown sock". Or in other words, your ass is turned inside out so it is hanging out of your butthole.
