Contexto cultural

The phrase is deeply rooted in British naval and market history. It is often linked to the 'cat o' nine tails' whip used for punishment on ships, though the market 'pig in a poke' theory is more widely accepted for this specific idiom. In American business culture, 'letting the cat out of the bag' is often used during product launches or when discussing leaks in Silicon Valley. It's a staple of corporate jargon. Australians use the phrase frequently in casual conversation, often with a self-deprecating tone if they are the ones who made the mistake. Because English is the lingua franca of business, this idiom is one of the most commonly taught to international professionals to ensure they understand when a 'leak' has occurred.
