The line comes from American Psycho, the 2000 film adaptation of Bret Easton Ellis's novel, where Christian Bale plays Wall Street banker Patrick Bateman. In his narration Bateman describes himself as an abstraction with no real self behind the mask he presents to others. Clips of that monologue later circulated widely in fan edits and social media posts about detachment, empty routines and the Bateman persona. Its flat delivery and bleak honesty keep it popular as a reaction sound long after the film's release.
