Joker is the codename of the protagonist in Persona 5, Atlus's stylish role-playing game released in 2016. In combat he shouts short exertion cries when attacking, and clips of those yells were ripped for soundboards and editing packs. Labeled variants like this one spread through gaming meme pages and TikTok edits, where the one-second length makes it perfect for cuts. It endures because Persona 5 remains a cultural touchstone and the raw shout works as a universal hype accent.
