Genji is a playable hero in Blizzard Entertainment's team shooter Overwatch, first released in 2016, where he is a cybernetic ninja who mixes Japanese phrases into his English voice lines. Arigato is the Japanese word for thank you, and this short line is one of his in-game acknowledgments. Online, Overwatch players and editors have reused it outside matches as a quick, respectful reaction to support, gifts, and helpful plays, keeping it popular because it is instantly recognisable to fans while remaining polite and easy to place in short videos.
