So, in other words, Moe is basically an incarnation in a woman of a man's fantasies about what, for him or for others, would be the ideal girl that would both depend on him and make him feel loved.
Moe charachters can look any age between 10 and 28(physical years) it's the cahrachteristics that make them moe, th charachteristics of dependance and "flawed perfection".
i.e. For most people, their perfect girl wouldn`t be perfect, they would have cute flaws. these flaws make them "perfect" for someone.
I am the squid of the vapor surrounding your dreams, sorrow, nightmares, and bootie pants. So watch out about that.
