Oh good God. Do not lump the Republic of Ireland with Northern Ireland. I know there's this whole duo-nationality thing because we're big whinges here but, truth be told, we suck something shocking compared to down south. It's a lovely place in the rest of Ireland but you see Northern Ireland? Gee whiz. Anyway, it's just our accents that are the God-awful one, proper Irish accents (for the most part) are lovely.
Apparently mine's posh but, of course, posh for a Belfast, Northern Irish accent. And aye; the dialect is completely made up of slang, even I can't understand it half of the time. I mean, I've had more than enough people honk their horns at me and as they drive off, they say, "Harggahaghblaag, yeeeeoooo!"
Er. Orite?
