The Great Cosmic Negro (GCN) is the black version of "The Man". While "The Man" is responsible for holding down and oppressing minorities, the GCN is responsible for the oppression of white people. He usually operated through liberal guilt, the "race card" or just bad luck.
I applied for the job but didn't get it because of some affirmative action clause. Looks like the Great Cosmic Negro is trying to keep me down.
