hubbub: [16] Hubbub is an Irish contribution to English. It comes from Irish Gaelic hooboobbes, which appears to be related to the Old Irish battle-cry abú. This was a derivative of buide ‘victory’ (a relative of which across the Irish Sea formed the basis of the name Boudicca or Boadicea, the Ancient Britons’ version of Victoria). English acquired the word (and the now disused longer form hubbuboo) in the mid 16th century, and originally used it for the ‘warcry of a savage tribe’; the modern sense ‘noisy turmoil’ developed in the 17th century.
1550s, whobub "confused noise," generally believed to be of Irish origin, perhaps from Gaelic ub!, expression of aversion or contempt, or Old Irish battle cry abu, from buide "victory."
