Hot, itchy asshole that results from incomplete ass wiping after dropping a bomb. Extremely common after the Hershey Squirts, and/or doing a lot of walking. Temporarily relieved by picking your ass, which in effect uses your underwear to get in a couple extra wipes (skids don't matter when in this condition). Vaseline can do wonders.
When at an amusement park and you use that shitty T.P. that is like newspaper and none of the shit from your ring sticks to it, then you go out and walk around for hours in the heat. You say to your buddy while picking your crack, "Man I have a Stingy Ring!"
