Mr Catra, born Wagner Domingues Costa, was one of the defining voices of Brazilian funk carioca from Rio de Janeiro, active from the 1990s until his death in 2018. His booming voice, explicit party anthems and catchphrases made clips of his live intros and ad libs circulate widely on Brazilian social media and WhatsApp. Vai comecar a putaria became one of his signature announcements, reused long after his peak as a shorthand for a baile funk starting and for any situation about to descend into playful disorder.
