Anjay is widely used online as an Indonesian slang-style reaction, and this short audio became popular in meme edits, reposts and casual soundboard use. Specific source details for this exact clip are unclear, but its spread follows the usual pattern of short reaction sounds: it gets clipped, reused and attached to visual punchlines. It remains popular because the delivery is instantly recognizable and easy to place on a reveal, boast or exaggerated moment, much like a vine boom sound in fast meme editing.
