obama-nigger
A word used by clueless rednecks who think they're smart because they heard it on a radio. It's for a guy who actually did some good, but they hate him anyway.
'Republicans call him a nigger because he's the only one who didn't let them steal all the money.'
'They're too dumb to see the change he brought, so they just call him a nigger and keep complaining.'
'Obama-nigger got the job, and now they're mad because he actually did something.'
