Racist of Color. A subset of Folks who categorized themselves as "of color" -- meaning non-white, never mind that white is, in fact, a color -- who have no qualms about being racist and holding ugly prejudices against others of another shade of color, or, most typically, against the white color. Sharpton, Jay-z, La Raza, & many Social Justice Warriors are but a few examples.
Mike: That homie just called me a cracker-ass white bitch for inadvertently cutting in line at the taco truck!
Hector: Just another angry butthurt Oakland R.O.C. Forget that worthless douche!

Roc
Roc'd- (Gerund) From the Simon and Garfunkel song "I am a Rock"; used when an individual self isolates from a group as a form of voluntary and unappreciated martyrdom, or a group isolates themselves from an individual because that individual poisons the group dynamic with their presence.
"We're so sick of Tyler trying to get attention by lying about breaking his ribs; it's all he talks about! He's about to get roc'd!"

"Robert's hasn't shown up to Clancy's Bar much lately, I hope he hasn't roc'd himself?"

"Andrew was worried he got roc'd when he didn't getting invited to game night."

"Shhh, don't tell Tyler...we roc'd him awhile back."

"I'm not allowed to create perpetually endless and nonsensical arguments while dominating the entire conversation...that's it, I'm roc'ing out of this group!"
