I googled up "Dut yee".
[Just a post from a Member on a Other forum.]
"Kawaii in Canto can be Dut Yee or Hor Oi.
Hor oi is the real saying while Dut Yee is the Slang-ish way."
I also though "Dut yee" meant Funny, but in a Cute way. >w<;;
[Which I always pronounced wrong, I pronounced it like 'Dat yee']
Cantonese has Jyutping neh?
