Oi turma is the Brazilian Portuguese greeting Mickey Mouse uses to welcome his audience, a localised version of his familiar hi everybody openings in Disney cartoons and Mickey Mouse Clubhouse. Mickey, created in 1928, has been dubbed into Portuguese for decades, and this short falsetto line spread online through Brazilian meme pages, WhatsApp groups and short video edits. Its brevity and warmth make it reusable far beyond children's television, as a friendly way to announce your arrival in any group conversation.
