"Fuckin' ay!" This also derives from a Scottish saying. Well, it can be argued that it may be Irish as it comes from a myth off of Rathlin Island, which lies between Ireland and the Mull of Kintyre. It may surprise you that it has no derogratory meaning. The story goes that there once lived a dark swarthy character, a sailor who originally arrived from England by the name of Timothy Fawkin. He never warmed up to the local population and as time went on rumours spread that he had the evil eye. Thus, is the origin of 'Fuckin ay'.
