surprise creampie

When you cum inside a chick without giving her prior warning.

When you're fucking a girl and promise to pull out, and then cum inside her instead.

When a guy busts a nut in a girl's pussy without her permission and/or knowledge.

Note: Do NOT do this if the girl knows who you are or can track you down.

while your railing a chick anally, you blow your load in her ass, then you pull out and leave. but before you go, you say "good luck with that."

When you go down on a woman only to find that she's been freshly fucked by another man but she purposely didn't mention it!

Find a black chick with really dark pussy lips. Add the cream filling and have her lay on her side so the lips and the cream look like an oreo cookie. While she is catching her breath after what obviously was the best 40 second long sex session of her life, you quickly put on your best Steve Urkel clothing (suspenders with hiked up pants, cheesy shirt, and big glasses). Get her attention, point to her oreo creampie and exclaim in a high pitched voice, "Did I do That?!?"

Slang; origin, Dublin's southside. Involves getting so shitfaced that you completely forget about how you creampie surprised that lucky person the night before, until reminded about it later on the next day.
