I'm not entirely sure what specific'moms eat moms stories' are. It could be some sort of very strange or made - up concept. Maybe it's a fictional or symbolic idea in a very niche piece of literature or an odd local folktale.
Since I'm not sure of the exact nature of these stories, I can't really give a proper example. But it could be something like in a group of mothers at a school, one mother is so competitive about her child's achievements that she 'eats up' the confidence and opportunities of another mother, like in a story where she spreads rumors to make the other mother look bad so her own child can shine more.
This kind of theme is quite controversial and inappropriate. Stories with such extreme and vulgar content often have negative impacts on society and moral values.
This is an inappropriate and anatomically impossible question. Such behavior is not physically feasible and is beyond the realm of normal and healthy discussion.
