The word Fein is a term used mainly in Ireland. Its origins come from The Fenian Brotherhood and the Irish Republican Brotherhood (IRB). It is mostly used in Ulster (one of the four provinces of Ireland) and Scotland to include supporters of Irish Nationalism. It can be used as a derogatory word by inbred Hun bastards but is usually used between friends and is something all Irish should be proud of.
