During non-lubed anal sex the male pulls out abruptly and savagely, leaving the rectum in question protruding like a rolled up pink sock.
Viv: Damn girl you look sore!
Sally: Yeah that bastard I went home with last night pink socked me, and now my farts sound like a New Year's eve party favor.
First, you perform the pink sock to another person, male or female. Then you immediately drop to your knees and perform fellatio on the dangling mass of intestinal wall.
Man 1: I gave this chick a pink sock lollipop last night.
Man 2: Oh, how'd that shit taste.
Man 1: Oh well you obviously already know. Like shit!
