Taking another shit after you've already wiped. Since double wiping occurs during the same trip to the bathroom, a sore butthole is usually the result
Stacey was just about done wiping after a satisfying shit when she felt another torpedo coming down the tube. "Damn" she thought, "now my ass is gonna be sore the rest of the day" as she proceeded to take a double shit.

A perfect shit, tapered evenly on both ends. Especially used when unexpected after a messy meal or night out.
Got up in the morning, took the most perfect double-tapered shit I've ever had in my life. True story. Who are the pitchers in this game? -George Brett
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
