The pink sock is when you are banging a bitch doggy style in the butthole, and right about the time your gonna shoot your hot goo, you donkey punch her hard enough to knock her out, and when her ass muscels tighten up it sucks the cum right outta your cock, then you QUICKLY pull your dick outta her ass. It will pull her asshole inside out and leave a pink sock hanging there.
I wanted to break up with my girl, so I decided to fuck her one last time just to Pink Sock her. Then I left her laying on the couch at her parents house, knocked out with her asshole hanging inside out.

Withdraw so fast (from the back side and often times without lubrication) that what is pulled out looks like a rolled up pink sock. Also known as an inverted starfish.
Dude, the donkey punch didn't knock her out like you said it would; instead she bucked me off so hard that she she gave herself a "pink sock."

When a guy fucks a girl's pooper loose, and pulls out quick so that her poopchute starts hanging out there like a pink sock. Basically if your pooper is this loose, you're a total skank.
After the frat boys took their turns on mindy's hiney, she ended up with a pinksock. Now she has a reputation as a buttslut, but I don't think she cares.
