Hullabaloo /hələbəˌlo͞o/ adj.

Definition:  Hullabaloo refers to loud, continued noise or a mixture of noises. It’s alternatively used to identify a state of commotion, excitement, or violent disturbance, or a loud noise made by people who are angry.

Etymology: The origin of hullabaloo is difficult to pin down and has generated varying theories over time. Many believe hullabaloo first appeared in a quotation by Scottish poet Tobias Smollett in 1762. The most accepted explanation suggests hullabaloo derived from a rhyming shout halloo-baloo!, possibly heard in English hunting fields. 

Alternatively, the Oxford English Dictionary identifies the old Scots term balow or baloo that appeared in some nursery rhymes as a possible origination, but the dictionary does not explain how baloo became hullabaloo or how or when the completely different connotation came about.
