Bad graffiti, such as that thrown up by a gangmember with no talent.
"Man! Look at all that nigger scratch on your wall!"
"I know, I need to get some Mexicans in here that care about their art."

"Looks like 2-Loc put up more nigger scratch on your property again"

Get the Nigger scratch mug.
for the most part accidental but a painful scratch by a black person's fingernail. This is assuming the stereotype that all black people have slightly long finger nails. Most commonly done in sports or in any activity in company of a black person.
Man! The nigger scratch I got in the pick up basketball game burns!

We were passing some papers around in class today, and when Fred passed the papers back to me he nigger scratched my eye.
