I had friends who were very black, he was from Nicaragua, she was from Panama. They called each other “Nigrito” and “Nigrita” – affectionate terms for a black man and woman.
My wife is hispanic, my mother-in-law calls my father-in-law "Negro" (Nay-gro) sometimes. My parents have a friend that has the nickname "Blacky". He's not black, that's just what they call him for no particular reason.
