Thanks Mikey Joe for clarifying that. Course it does muddy the waters a little more since there was no lyric sheet. Sounds like a good album though.
The word sagacious has been put forward as a possible source for sagosha/segotia or whatever the spelling. Given the Dublin penchant for a play on words, how about this. The words 'precocious' and 'sagacious' are not too far apart in meaning. Could it possibly be that it is a combination of the two, making it 'sagocious' and hence 'Me Oul Sagocia' which would not necessarily be a term of endearment. I supppose it would depend on who was saying it and who they were saying it to.
My father sometimes used a phrase 'don't be so stroctamocious.' It is not in any dictionary I have. To be honest we were never sure what the hell the word meant, but we knew what he meant. He was saying "don't be annoying me" or "don't be a pain in the neck", or a clip on the ear was surely on it's way.
As Martin Ryan has pointed out the whole thing is probably just one of life's mysteries. Still, it makes for an interesting discussion.
By the way, I have never heard 'Dubs' used in reference to toilets. 'The Jacks' yes, but the other one is a bit far-fetched.
