I walked into walmart on the south side and was blown away by the niggertivity inside, a black woman took off her weave and used it to administer a beat down on her baby daddy.
Two guys in a truck: one sees a black man half walking half dancing while jaywalking across the street, says to other guy "check out this niggertivity"
"Niggericity" is an expression of one's level of niggerness, quantified by a numeric scale of 0-10.
Wow, my neighbor My'Queshia has 5 kids by 5 men, and sure spends a lot of her welfare checks on malt liquor. We're dealing with a niggericity factor 10.
My cousin Bjorn just moved here from Sweden. He's a Java developer with a Ph.D., drives a Volvo, and has a niggericity factor of 0.
