Little is known about who first recorded Borrus or where the name came from, so its history is mostly in how it circulates online. The clip spread as a WhatsApp audio, forwarded between chats and later saved to soundboards where short voice reactions are collected. At about fifteen seconds it is longer than a typical button sound, which makes it useful as a full reply rather than a quick effect. It remains in use because the word is easy to recognize, hard to place, and funny without needing translation or background.
