D.Va, real name Hana Song, is a playable hero in Blizzard's hero shooter Overwatch, released in 2016, known for her mech, gamer background and cheerful voice lines in several languages. Short lines like this ciao greeting were clipped from in-game audio and shared on soundboards and in fan edits, where their length made them easy to reuse as reactions. The clip remains popular because it says hello or goodbye in less than a second, works without context, and is instantly identifiable to players who know the character.
