Coringa domingo a noite circulates mainly as a WhatsApp audio in Portuguese speaking group chats, where short named voice clips are forwarded as reactions. Coringa is the Portuguese name for the Joker, and domingo a noite means Sunday night, so the title itself works as the joke and the search phrase. The clip has spread through reposts on soundboards rather than an official release, which is typical for WhatsApp audios. Its appeal is timing, dropped at the end of the weekend when friends are tired, restless and joking about going back to routine.
