The phrase comes from Spanish language television humour shared in Argentina, where short shouted lines are often clipped and reused as reaction audio. Online, the sound spread through soundboards and chat groups as a shorthand for a party getting out of control. Its appeal is timing rather than context, so creators use it even without knowing the original scene. The two second length, clear shout and recognisable fiesta wording keep it circulating in meme edits, party videos and Spanish language group chats.
