Bilu circulates mainly as a user-uploaded soundboard clip with no single documented source, which is common for ultra-short meme audio. The file is shared, replayed and remixed across meme edits, shitposts and short-form videos, where the humor comes from repetition rather than any original scene. Because the name itself is catchy and easy to shout, it works as a standalone catchphrase that needs no translation. Its continued use is driven by creators reusing it as a familiar in-joke.
