The 'YOU IS A' meme is a popular spin-off from the 2017 indie hit Cuphead, celebrated for its authentic 1930s rubber-hose animation style. The template usually features a screenshot of a boss—most famously The Devil—pointing directly at the screen with the grammatically broken text 'YOU IS A' displayed prominently. While the game features legitimate taunts on its game-over screens, this specific version became an internet sensation for its blunt, aggressive, and often absurdly simplistic insults. It is widely used across social media to dismiss an opponent's argument or to mock someone with the dramatic flair of a vintage cartoon villain.
