A person of both black and mexican
heritage. Either of parents of either race. This term is
interchangeable. Some people of black and mexican
heritage will take offense to this term. Depending on who you talk to.
Some prefer "Mexigro" (meaning both mexican and both negro), and others just refer to themselves as just plain biracial.
Some children born of both black and mexican heritage are thought to have "good hair". A term that many blacks use for easy, manageable, "white" hair. This however is a only semi-true.
