The sound comes from the prank tradition of Programa Silvio Santos, the long running Brazilian variety show hosted by Silvio Santos on SBT, famous for its Câmera Escondida hidden camera segments. Those pranks became a staple of Sunday television in Brazil and later spread widely online as short clips and reaction sounds. As editing culture adopted the cue, it moved from television into WhatsApp groups, memes and short form video, where it now works as shorthand for a classic, good natured pegadinha.
