The phrase comes from JoJo's Bizarre Adventure: Golden Wind, the fifth part of Hirohiko Araki's manga adapted as an anime in 2018. Bruno Bucciarati, leader of Giorno Giovanna's group, uses Sticky Fingers in close combat and shouts 'ari' with each strike before finishing with 'arrivederci,' Italian for goodbye. Clips of the barrage spread through anime edits, JoJo fan communities and soundboards, where the long build and polite final word made it a recognisable shorthand for a stylish beatdown.
