fenian

Contrary to common belief, fenian is not a random slang word for catholics, before the ira, there was the fenian brotherhood, fenian being gaelic for brave young warrior, when a british army person was apprehending a member, they used the term, "you fenian bastard" this has endured, it isn't a random term, or a chuckle for the irish about how it's secretly a compliment, it's simply a legacy from the insults for the fenian brotherhood
