"China doll!"

I was walking in Fort Greene Park, on my way home around 3pm. As I passed by the men's restroom, an old man (in his 60s?) was about to get on his bicycle. He made eye contact with me and said "China doll!" and then after I walked passed him, he said "China doll. Sucky, sucky. F*cky, f*cky." I did not turn around.
