Chop Suey is a 2001 single by the Armenian American metal band System Of A Down, released on their album Toxicity. Known for its abrupt tempo changes and the opening shout that launches the track, it became one of the band's signature songs and a staple of early internet music sharing. Short excerpts later circulated on soundboards and in video edits, where the familiar burst is instantly recognised by rock and meme audiences even without the full song playing.
