YOU'RE MEXICAN STOP SAYING NIGGA. If you don't identify with African or black Ancestry stop using this term. Not appropriate and not cool. Cultural Appropriation at its finest and you are being an ignorant culture vulture. If you were raised black or african and that is your sangre then go for it you can say whatever is in your cultural limits because you make up that culture however the caveat is if you were not raised or you know you ain't black then quit being ignorant.
