That bitch Kasey is such a goddamn Cunt Shitter!!
To create a masterpiece in the lavatory in the style of Jackson Pollock by using what would be an otherwise watery, splattery deficate and repurpose it as art.
Man 1: Whoa Nelly! Do not go in there. Some dude JP’d the shitter.
Man 2: JP’d the shitter?? I don’t get it.
Man 1: My dude, you need to broaden your cultural exposure.
Paul Jackson Pollock was an American painter and a major figure in the abstract expressionist movement. He was widely noticed for his technique of pouring or splashing liquid household paint onto a horizontal surface, enabling him to view and paint his canvases from all angles. Therefore when you JP the shitter, you pay homage to the man responsible for such modern masterpieces as Autumn Rhythm, Convergence and Number 1.
Man 2: As opposed to Number 2. My dude, I apologize for my ignorance. I had no idea that shit could be art.
