There is no widely documented film, television or music origin for this short clip, so it is best understood as an internet soundboard joke built around a familiar Mandarin childhood phrase. Short, easily recognised phrases travel well in memes because they need no translation for regular viewers and can be dropped into almost any edit. On soundboards and in short videos, Niao Niao is used as a quick reaction rather than a story element, and its staying power comes from that simplicity: one innocent word, one awkward idea, and an instant laugh.
