Yare yare is a common Japanese expression of exasperation, roughly meaning good grief, and it became closely linked with Kusuo Saiki, the psychic teenager at the centre of The Disastrous Life of Saiki K. The manga series began in 2012 and its anime adaptation followed in 2016, with Saiki using the phrase as a weary response to the chaos around him. Clips of the line spread through anime compilations and short-form edits, where it now functions as shorthand for resigned disbelief even for viewers who have not watched the full series.
