Chicos de la Obra circulates as a short Spanish-language WhatsApp audio rather than as a line from a widely known film or television show, and its exact original recording is not clearly documented. That low-key, chat-first life is part of its appeal: it is passed between friends, dropped into group conversations and reused as a quick reaction to work, building and everyday job-site humour. Because the phrase is instantly recognisable to Spanish speakers, it keeps working even without a famous source behind it.
