A nigga baby is a dark complected beautiful child that wears a pamper and no shoes. He or She will probably have a cajun uncle or some kind of racist relative that gave them that nickname. A niggababy is not a racist term even though a racist may have created the term. The term nigga has evolved and now is a term or expression of endearment. A niggababy does not hav to be black or dark but should at least be brown either on the outside or on the inside.
"Say, where is that little kitty? I can hear her crying."
"oh, the last time I see the kitty was when Niggababy was pushing it in a stroller in the kitchen."
"oh, ok then, the kitty's fine....NIGGABABY!!! you better be nice to that baby kitty!!"
