Thanks very much, SBE! I never thought of the kaliarda. That sparks off another association. When I asked for the Greek for 'Ooh, get you!'--still unanswered--I was reminded of the rough Turkish equivalent, the ever versatile vay, which is also, apparently, the Romanian cognate for wow.
You can multiply these as much as you want (& 'be' as well), which is like saying:'Oooooooooh'. There is also the sarcastic 'Canım' which although meaning darling, may be used by whichever gender to describe whichever gender.
So 'get you' could simply be a sarcastic 'woooooow' or 'Bowie'. Is there a Greek word to match these suggestions?
