"His Ass Is Not X" is a popular internet slang template used to humorously point out that a character—most often a confused-looking animal—is completely incapable of the task they appear to be performing. The format gained significant traction on platforms like Twitter and Tumblr, frequently featuring cats staring at computer screens or books with captions like "His ass is NOT reading." It relies on the absurdity of attributing human intellect or complex actions to pets. Over time, the meme evolved to include celebrities and fictional characters, serving as a versatile way to mock someone’s perceived incompetence or fake productivity in a lighthearted, dismissive tone.
