Green Monster 

Leaving a turd laying across a rack that goes above a toilet when the rack was blocking the upper tank area of the toilet in the process of attempting to leave an upper decker (top shelf) in someone's toilet.

Person 1: did you upper deck the toilet at travis' shitty party?
Person 2: i couldn't, there was a toilet rack blocking the top part so i left a green monster instead.

occasionally paired with the Liberty Bowl to extend bowl life

challenging hit for some, as it held too little water to provide chilly nice but a very useful tool for those who practiced with it often
