1. Used When you are out of toilet paper so you turn on the shower and wash out the crack of your ass.
2. Also used when you take to nasty of a poo that you can't wipe all of the poo out of your ass crack and have to wash it out.
'Fred took a massive shit, he tried wiping but the toilet paper would only stick to his ass so he turned on the shower and took a "poop-n-shower".'
