The line comes from Bluey, the Australian animated series created by Joe Brumm that premiered in 2018, where Bandit Heeler is the playful dad of Bluey and Bingo and is voiced by David McCormack. His easygoing catchphrases became widely clipped on social media as families and fans shared short moments from the show. This goodbye in particular circulates as a standalone reaction because it is brief, recognisable without any setup, and works for both children quoting the cartoon and adults using it ironically in everyday edits.
