As far as I can work out after living and working among them for 15 years, sophistication among this closed group of people is exhibited by the extent to which you can mangle and shorten your vowel sounds - hence saying that there was good snOW on your skiing trip marks you out as an uncouth Nordie; but if you say there was g'd sn' - well now you've arrived in Killiney aka arroyved in Kloyney. It's a continual process of phonetic self-censorship. Here are some I've noticed recently; I'll add to this very occasionally:
------------------------------------------------------------------------------
Aguh = ago
Aehyt = out
Baat = about
Coffee = café
Cull = cool
Cole = call
Dehyn - down
Ex-soy-ted = excited
Fall = full
Hoy = hi
Hyse = house
Gom = com [as id "dot gom"; cf. "scone" = "sgown"]
K-omponent = component
Mald = mild [there's a weather forecaster on RTÉ who always says that 'toenat, there will be mald conditions ...']
Ness = nice
Nuh = now [as wth "snow", the "ow" sound is deliberately not completed or rounded out - the mouth remains hanging open to create the desired posh / can't be bothered effect]
Oh-keh = oh-kay
Ore = or
Rum = room
Ryndabyte = roundabout
Sgown = scone
Snuh = snow
Toenat = tonight
Toff = tough
Wordrobe = wardrobe
Yaheh = yeah
Whal = while
