Hi John. I don't think there are any sources for that word anyway. You're obviously not from Ireland yourself or at least not from Cork or you'd know it yourself. I think it's sad that the old ways of speaking are being drowned out by the new Americanized ways of speaking, so please don't try to "academize" how the old people did and do speak still. I have no idea why you have any suspicions over it, you can ask anyone who has ever heard it what it means, without having an actual clue yourself what you're talking about.
