A "big nig" is a large black person. This only includes African-Americans and straight up thug life goons such as some Haitians. Most "big nigs" are very dark skinned and actually black. They are also very muscular while some are obese.
I was watching boxing, and it was mostly big nigs beating the shit out of each other.
