A kerfuffle is some kind of commotion, controversy, or fuss. If you read about a scandal in a newspaper, it could be described as a kerfuffle.
Kerfuffle is a humorous-sounding word for a mostly non-humorous situation: some kind of disturbance, scandal or mess. However, a kerfuffle usually isn't 100% serious. People talking loudly in public could be making a kerfuffle. If a politician says something embarrassing by accident, it could cause a kerfuffle. Often, people use this word when they think people are making too big a deal of something, as in "What's the kerfuffle all about?"
