This sound is best known from meme edits and soundboards rather than from one clearly documented single source. Online, it is usually labeled with terms like chinese gong sound effect or stereotypical asian music, which helped it spread through short-form parody videos, reaction clips and gaming edits. The mix of a loud gong and brief musical phrase makes it easy to place on a hard cut, so it keeps circulating as a fast shorthand for an exaggerated reveal or cultural reference joke.
