The phrase is the signature catchphrase of Jotaro Kujo, the protagonist of Stardust Crusaders, the third story arc of Hirohiko Araki's JoJo's Bizarre Adventure manga, which began in 1989 and was adapted into a television anime in 2014. Translating roughly to 'good grief,' it captures Jotaro's stoic, easily annoyed personality. English-speaking fans embraced it through subtitled episodes, memes and reaction compilations, and it became a staple of anime soundboards. Short, dry and instantly recognisable, it endures as shorthand for cool-headed exasperation.
