The phrase ching chong has long been used in English as a mock imitation of Mandarin and Cantonese speech, and it later spread online as a short meme audio clip. Because the recording is under a second, it works like a reaction button on soundboards and in short form edits, where creators reuse familiar meme sounds to signal a joke instantly. Its continued use comes from that recognisability rather than any single film, song or show, and it often appears alongside other meme sounds in compilations.
