a loud noise or commotion
hullabaloo - fuss
The informal word ‘hullabaloo’ refers to a lot of fuss, sound, or disturbance typically made by people who are angry or excited about something. It generally deals with things that are quite trivial, so if the commotion was to lead to violence, this term would not be appropriate to describe it. Most commonly used in spoken English.
