My dad always called me "sweetcakes!" I loved that...and miss it a lot now that he is gone.
DH calls me "babe" most of the time, my sister calls me "bess" and all of my siblings lovingly refer to me as "gah-leh-gai" .... Cantonese for "curry chicken". It was their clever little play on my cantonese name. When I was in HS, my brothers called me "hips". It was their sweet little way of gettin me really hacked off! Love those guys!
