What is a hooley? Where does the word come from?
Everything about the word hooley is disputed, including the spelling. Hoolie or hooley? Or even huly as it first appeared Bartlett's Dictionary of American English in 1877.
Origin
A hoolie is now a generic term for a raucous part. The word is most commonly used in Ireland, but can be traced back to Orkney Scots, where it meant a strong wind or gale.
This derivation is evident in the idiom blowing up a hooley.
