Nephew to the upper decker the catchers mit may be attained by layering toilet paper extending from one side of the bowl across the water and onto the other side of the bowl forming a soft sturdy pad. Proceed with your normal defecation but cease to flush. You now have a permeating pile for all to enjoy. Most commonly found in road side rest areas.
"OMG! WTF! This is the stalest catchers mit ive ever dealt with!" Dale the janitor.
A large wad of toilet paper that you place into the blue water of a recently serviced porta-pottie just before you take a dump, so when the turd drops into the blue water it doesn't splash up to your butt. Giving you smurf butt.
I had a turtle head poking so I ran to the porta-pottie, only to find clear blue waters. So I made a catchers mitt and dropped it in.
