Always known Kahki to be imported via the British army in India from a local dialect (not sure which one.)
Shit'ucks or shite'ucks is a curse that my dad, a British army man, frequently used. It is apparantly a bizare rhyming slang twist on Kite Hawks, a bird of prey found in the Far East. These were apparantly not liked for their stealing of food.
Having lived in Hong Kong for some time I have not once known one of these fish-hunting birds of prey to come within half a mile of me, let alone steal food like a seagull might. What is more strange is that my dad found it far more acceptable to say Shitocks in front of his kids rather than the inoffensive Kite Hawks. Another one he has taken to of late is "Fester me Doglets!"
BTW Don't let the truth spoil a good story.
