'bamboche' originates from French, specifically the word 'bamboche', where the verb 'bambocher' meant 'to make merry' or 'to revel'.

'bamboche' was used in French to denote noisy revelry and was borrowed into English in literary and travel-writing contexts in the 18th–19th centuries, retaining its sense of a boisterous party.

Initially, it meant 'a merry-making or noisy revel' in French, and in English usage it has largely retained that meaning, though it remains a rare/loanword in modern English.
