The 'They Called Me a Madman' meme originates from the 2018 Marvel blockbuster Avengers: Infinity War. During a confrontation on the ruined planet Titan, Thanos explains his tragic backstory to Doctor Strange, noting that his warnings about overpopulation were ignored by his people. The scene has since become a staple of internet culture, used to depict situations where a person's unconventional ideas or predictions eventually prove to be correct. It is the go-to template for anyone wanting to express a sense of smug vindication or to highlight a 'mad' plan that actually makes perfect sense in hindsight.
