This audio is widely used online as an Indonesian disbelief reaction clip, especially in meme edits, reposts, and chat-style videos. The phrase “boong, yang bener” literally signals that something sounds false or hard to believe, which is why creators use it as a quick comedic response. Even when the exact original recording source is not clearly identified, the sound keeps circulating because it fits a universal reaction format similar to a bruh moment or a buzzer-style callout.
