The clip comes from Programa Jurandir Mitoso, a show on Rádio Cidade AM 860 kHz in Fortaleza, Brazil, and its file tag dates the recording to April 2015. The voice behind the 'ihuuu' is the station's beloved véio do forró, an old-school forró personality known for his rowdy shouts. Short radio moments like this travel fast in Brazil, and this one became a staple of meme pages and WhatsApp audio collections, where the two-second yell works as a pocket-sized party starter that needs no translation.
