A furore is a sudden, noisy burst of public anger about something that has just happened — a decision, a remark, a scandal. A large group is upset at once, and the noise is the story: protests, angry posts, headlines. British English keeps this spelling; American English more often writes furor, and says it with two beats, not three. Newspapers love the word because it sounds like the heat of the moment. Though actually, people also stretch it to a big public stir that is not only anger — a craze, a fuss — but the core picture is a crowd suddenly furious. It is a fairly formal, written word; in speech someone might just say a huge row or everyone was furious.
