The line comes from JoJo's Bizarre Adventure: Golden Wind, the fifth part of the series, where Bruno Bucciarati leads the Passione gang and serves as a mentor figure to Giorno Giovanna. Arrivederci is simply Italian for goodbye, but in Bruno's composed delivery it becomes a memorable sign-off for anime edits and soundboards. As Golden Wind clips spread through fan videos and meme pages, the farewell joined other series staples such as Giorno's Theme, To be Continued and Za Warudo, and it remains popular for closing scenes with style rather than noise.
