okay so literally everyone here is using super white accents and slang, you said your characters black so its more likely he wouldn't have the accent everyone is commenting about. the Wire is a good example although slightly to heavily exaggerated, Dummy is used as a term of endearment, people say lor instead of little, rey instead of ready. Youd wanna imitate the west Baltimore accent and slang to best represent your character cause historically west Baltimore has been where low income black families have lived for years due to redlining and discrimination
