Celebrated every June 16th. Used to reject the idea that Papyrus from Undertale is too innocent to say “fuck” and is easily corrupted. Papyrus is drawn/written doing things like arson, gambling, or, as is the namesake, saying fuck.
Person 1: Why are you drawing Papyrus robbing a bank and swearing?
Person 2: It’s Let Papyrus Say Fuck day!
