The Patrick Bateman 'Ooh Face' originates from the 2000 cult classic film American Psycho, specifically during the famous business card comparison scene. In this moment, Patrick Bateman (played by Christian Bale) reacts with a mix of intense envy and visceral satisfaction to a colleague's superior business card featuring a 'Pale Nimbus' color and subtle watermark. On the internet, this specific facial expression has become a staple reaction image for expressing profound appreciation or mock-sensual pleasure toward something of high quality, aesthetic beauty, or impressive craftsmanship. It is frequently used within 'sigma' culture and general meme circles to highlight the humor in being overly obsessed with trivial details.
