To have cum in the ass of a dark-skinned individual, pulled apart his/her ass cheeks, and licked out the "cream filling". If one is feeling particularly adventurous, one might then push the ass cheeks back together and eat them, whatever the fuck that means.
"So you came in her ass. What happened then?"
"'What happened then?' What the fuck do you mean? I fuckin' Oreoed the shit outta that bitch! Literally!"
