A pregnant woman who believes the world revolves around her and the spawn baking in her uterus. These women most likely had large and elaborate weddings with several rules and regulations for the groom, wedding attendants, and the guests (also see Bridezilla or beebee). Attention must be on her at all times. Caution, tantrums will ensue and Armageddon will occur if she does not get what she wants. Women can become one with no warning at any time from conception to birth.
