An ignorant nigga...someone (anyone, not limited to those of African American descent) who perpetuates and overexeplifies the stereotypical behavior known to being a nigga. Such as being loud in public, doing wraunchy dances in public, extra flamboyant hair colors, cussing at kids in church, sleeping after all meals, cussing out regular people cuz they left out the extra hot sauce you ordered with your super sized box of chicken wings, stealin cable and getting your telephone line cut back on in your childs name, and the list could go on forever and ever, Amen.
"I was in the back of the library n I heard Shante and Mercedes screamin n fightin in the front...Now that was some nignorance."
