When you are sweaty and taking a sloppy shit, you attempt to wipe your ass upon explosive completion; however your ass pit is so damn soupy that even sweat wipes won't cut it. Your first attempt to wipe your ass only smears your shit around your b-hole, worsening the situation.
Bro, I just dropped a dang old sloppy joe in the commode and when I tried to wipe my ass, it totally resulted in a shit shmear.
