The sticky, often viscous flow of ejaculate and vaginal fluid which discharges from the vagina after a man ejaculates into the vagina. Poon goo is not to be confused with a "creampie," as that is generally just the ejaculate seeping from the vagina. Poon goo usually occurs later after intercourse than a "creampie," and is more similar to "flowback."
So, this chick rode my rod and I busted in that shit. She then laid on top of me to cuddle or something. Next thing I know, I woke up covered in poon goo!
