Thriller is the title track from Michael Jackson's best-selling 1982 album, built around a horror-movie story of dancing zombies and a late-night fright. Its closing evil laugh became one of the song's most quoted moments, instantly recognised even by people who have never heard the full track. As Halloween edits, reaction videos and short-form memes reused the clip, it turned into shorthand for a spooky twist or a villainous reveal. Decades later it still works because the sound alone carries the whole Thriller mood in just a few seconds.
