When, seconds after finishing a shower, a big dirty poop begins slamming around in your intestines. After jettisoning the egregious turd and wiping, you still feel unclean, so you are forced to return to the shower and soap up the inside of your butt crack again, after having just done so minutes earlier.
Guy 1: Hey man, why'd you take two showers? You're running up the water bill!

Guy 2: Fuck off, man, the sloppiest turd you've ever seen or smelled hit me right after I got out the first time, so I had to do the double butt scrub.
