muddy butt duck walk
This is a shameful act that only happens in desperation when you are home alone and have completely run out of toilet paper. With your pants around your ankles, squat walking, and your hands spreading the butt cheeks so you don't smear shit everywhere, you walk this way to your roommates bathroom to finish the job.
Greg had to do the muddy butt duck walk to my bathroom to get more toilet paper.
