look up any word, like plopping:
 
1.
Short, poetic like inscriptions scribbled with sharpie marker on bathrooms stalls/walls, that are appropriately of toilet humor nature. Bathroom poetry can be found in the restroom facilities of gas stations, campgrounds, bus depots, schools and airports, with the most original works done by the cleverest of bathroom patrons. Great for something to read while pinching one off.
Bathroom Poetry:

"Here i sit, so broken hearted, paid a dime, but only farted."

"Some come here to read the walls, I come here to jiggle
my balls."
