A kerfuffle is a fuss: noisy, busy, and not really needed. Papers fly, people talk over each other, someone is a bit offended, and then it dies down. It is informal British English; Irish and American speakers use it too, often with a half-smile. You would not put it in a police report. You would say it about a meeting that got silly, or neighbours arguing about a parking space. Though actually, a kerfuffle is smaller than a riot or a crisis, and the word makes the trouble sound slightly comic. If something is truly dangerous or cruel, kerfuffle is the wrong word — it shrinks the harm, as if we were laughing.

一陣騷動；小風波（帶「鬧哄哄、有點小題大作」的口吻，偏英式口語）
