Bart, Get Out! I’m Piss!
Bart, Get Out! I’m Piss!, often quoted Get Out Bart! I’m Piss!, is a catchphrase originating from a fan-made pornographic Simpsons comic that depicts Bart walking in on his sister Lisa urinating naked on the toilet to which she shouts, “Bart, get out! I’m piss!” The phrase is often used in reply to people spamming 4chan’s /b/ and /co/ boards with illustrated porn of low-quality and comics from the site Drawn-sex, where the original comic came from.
