Jet-Vac is a Skylander from Activision's Skylanders franchise, a series of toys-to-life video games built around collectible heroes battling the villain Kaos. Kaos is the franchise's recurring antagonist, so Jet-Vac calling his name captures their long-running rivalry in a single shout. Fans lifted the short line into edits, streams, and meme videos, where it works as a quick way to blame Kaos for trouble or announce a villain's arrival. Its short length and clear delivery keep it useful for reaction clips and gaming content.
