The audio comes from I Kill People, a comedy rap track by Canadian comedian and musician Jon Lajoie, known for deadpan songs that treat shocking subjects as throwaway jokes. Short excerpts began circulating as soundboard clips and reaction sounds, while subtitled versions also spread online and widened its audience beyond English-speaking viewers. Its appeal has endured because the brief, matter-of-fact delivery is instantly recognisable and easy to drop into edits. Creators still reuse it when they need a dark, absurd punchline that needs no setup or explanation.
