Anya Forger is the adopted daughter in Spy x Family, a manga and anime series centred on a spy, an assassin and their telepathic child pretending to be a normal family. Her cheerful, slightly mispronounced way of speaking became one of the show's most imitated traits, and short voice clips of her quickly spread through anime edits, reaction videos and social media compilations. This okeydoke line works as a compact version of that charm, which is why creators still use it to signal playful agreement without needing any context from the series.
