homesick - a culchie is someone who lives in a hole-in-the-hedge in the arsehole-of-nowhere, to get a few more sayings in there. Probably comes from an abbreviation of "agricultural", and sums up anyone who speaks in a broad country accent, comes from a farming background (or according to "townies", if they don't come from the city) and drives their tractor to the local disco. Some of the culchies in Norn Ireland have a term for the townies, calling them "Frankies". For ages I puzzled over this - people assumed it was because a considerable amount of them were called "Frankie" and shouting it to their like-named mates in a broad Belfast accent. Turns out it actually stems from the War when people were evacuated from the cities and had their papers franked to indicate they were evacuees.
