Definition- A black man who speaks Ebonics.
Variations and related words- "Nigga" "Wigger" "Nigkwahh" (spelled phonetically, not usually written).
Origin- During times of slavery, English had developed a dialect called American English which developed a subdialect called Ebonics (African American Vernacular English), and the word "nigger" was used by white people to refer to black people. Ebonics turned the word into the commonly used modern form, "nigguh." Over time, the word was used as an identification of a specific group of people. It was no longer "nigger" used to racistly refer to black people.
