Joseph Joestar is the hero of Battle Tendency, the second part of Hirohiko Araki's JoJo's Bizarre Adventure manga, first published in the late 1980s and adapted into anime in 2012. Joseph is famous for his loud English exclamations, including 'Oh my God' and 'Oh no', delivered with exaggerated pronunciation that fans quickly clipped and shared. As reaction videos and anime edits spread on YouTube and TikTok, the line became shorthand for comic panic, separate from its original scene but tied to Joseph's cocky, trickster personality.
