look up any word, like dirty sanchez:
 
1.
When a girl sucks your shit covered dick after you fuck her in the ass, and you cum in her mouth. The gooey mixture of fecal matter and semen is reminiscent of an oreo pie.
Brian: Dude, I met this cum dumpster at the bar last night. She's a freak man, lemme tell you.

Trevor: Shiiit man, give her some of that oreo pie!!

Brian: You sick bastard! I'm gonna do it.
