Mussum was a Brazilian comedian best known as a member of the comedy group Os Trapalhões, whose sketches and catchphrases became part of Brazilian popular culture. Short audio clips of his distinctive voice have continued to circulate long after the original television broadcasts, especially in WhatsApp chats and Brazilian meme pages. Ta duro, a casual way of saying things are hard, fits that tradition perfectly, because it is short, expressive and instantly recognisable to Brazilian audiences. Its lasting appeal comes from that mix of nostalgia and everyday relatability.
