Do vaginas poop?

No. Women have there ovulation out their vagina. ^That doesn't make sense. You suck. A correct answer follows...

Yes, but only at one or two specific times in their lives. The time that women are guaranteed to poop out of their vaginas is when they are pregnant. While babies are in the womb they secrete quite a bit of so called "poop." Then when babies are born, all of this poop (along with placenta etc..) comes out. Hence the aptly named phenomenon known as "vaginal pooping."
