Hahaha it means nothing…
Renoi means “black” and black people but it’s verlan language. Verlan is a kind of french where you invert letters or syllabus in fact. It comes from “banlieue” (suburbs) of Paris. So renoi is noir in standard french. Then, renoise could be the female word for renoi but I’ve never heard it, and I think it’s not used at all because the female word for noir is noire…
Women = femme = meuf
Shit = merde = demer
etc…
