Plants vs. Zombies is a tower defense game released by PopCap Games in 2009, with music composed by Laura Shigihara. The Disco Zombie is one of its themed enemies, arriving with disco styling and summoning backup dancers, so its short theme works as an audio shorthand for that joke. As clips and gameplay edits spread on video and soundboard platforms, players kept reusing the groove outside the game for entrances and dance gags. Its link to a well known game and a clear character keeps it recognisable years later.
