the act of using surrounding noises to strategically defecate in a public restroom. taken from Tim Robbins' escape from the fictitious "Shawshank
Prison," wherein he bludgeones a large sewage
pipe with a rock, striking the
pipe only when the thunder from a lightning bolt is loud enough to mask the noise of his stone as it strikes metal.
man, i had to crap so bad! but i knew with only
one other guy in the bathroom,
shawshank shitting
just wouldn't be an option.
