Did you know the character "Shrek" is neither fat or obese, but is actually pregnant from Fiona's child? It was explained in the Dreamworks Immersive Cinematic Kit (DICK), which was included in the Shrek 4Ever After Blu-Ray, that ogre males carry the child of the female, and after ejaculation, the male ogre's donger must remain inside the female ogre for extended amounts of time until the fertilized egg can travel back through the male's urethral tract and into his womb.
To achieve this, ogres have evolved a remarkable system where the vaginal muscles clamp down on the male's phallus to keep it inside while the egg fertilizes and transfers back to the male. They give birth through the anus, which has caused male ogres to gather with his male tribe members to have a fully grown onion, which is roughly the size of a newborn ogre's head (the largest part of the body at birth) to prepare his anus for the pain and stretching he must endure when giving birth. Thank you for your attention.
