Ka-chow became Lightning McQueen's trademark line in Pixar's Cars, released in 2006, with Owen Wilson voicing the rookie race car who learns humility in Radiator Springs. The phrase was built to sound like a flashbulb and a boast at once, which made it easy to quote outside the film. Clips and remixes spread it across YouTube, TikTok and soundboards in the 2010s and 2020s, often spelled kachow or kachowe, where it now marks any overconfident entrance, pose or win.
