The American Psycho meme featuring Patrick Bateman (played by Christian Bale) stems from the 2000 cult classic film of the same name. While the movie is a dark satire on 1980s yuppie culture and consumerism, it found a second life online through reaction images and 'Sigma' edits. From the iconic business card jealousy scene to Bateman’s deadpan expression while listening to Huey Lewis and the News, these templates are used to signify high-brow taste, social detachment, or ironic superiority. The meme peaked in popularity during the early 2020s, becoming the face of the 'Sigma Grindset' subculture, often used to mock or celebrate hyper-focused, antisocial, or perfectionist behaviors.
