Yare yare is a common Japanese expression meaning good grief, and it became closely tied to Kusuo Saiki, the psychic protagonist of The Disastrous Life of Saiki K., who uses it whenever his classmates drag him into absurd situations. The anime, adapted from Shuichi Aso's manga, made the deadpan line a shorthand for resigned annoyance among fans. Clips of the sigh spread through anime edits, reaction videos and short-form posts, where it now works even for viewers who have never watched the series.
