Many apologies, I admit to being linguistically challenged , scatologically speaking.
Now that I have seen it, karenmac60 is quite correct....
doo keech is the appropriate phrase.
heathfield's phonology is also completely accurate..the 'ch' in 'keech' is pronounced as the 'ch' in 'loch'...though how anyone in Scotland would pronounce a 'ch' differently has got me foxed. Except maybe in 'Christmas' ..but as everybody knows, new year or Hogmanay is the celebration in Scotland, not Christmas.
Isn't this a lot of nonsense!!!
