Persona 3 is a role playing game in the Shin Megami Tensei series first released in 2006, following the SEES team as they fight Shadows during the Dark Hour. Yukari Takeba and Junpei Iori are two of its main party members, and their bickering became a defining part of the group's dynamic. Yukari's nickname Stupei for Junpei stuck with fans and turned short exchanges between them into shareable clips. This moment spread through gaming soundboards and fan edits because their chemistry works even without gameplay context.
