As a standalone audio clip it spread through short form video and chat soundboards, where its short length and clear affectionate meaning made it easy to lift and reuse out of context. It remains popular because the meaning is understood instantly across Malaysia and Indonesia, and the tone carries the joke or the sweetness even for viewers who only catch the final word.
