Since I'm not sure exactly what is meant by 'ate out my mom stories', but if it's about eating out with mom, an example could be going to a pizza place and mom insisting on trying a new, strange - looking topping.
Well, without more context, it's difficult to say precisely. 'Ate out my mom stories' might be stories where the narrator went to eat at a restaurant or some place outside with their mom. It could involve things like the conversations they had during those outings, or perhaps some funny incidents that occurred while they were out eating.
Sharing such stories is completely inappropriate and violates moral and ethical boundaries. This involves vulgar and inappropriate content that should not be spread or discussed in public or private in a positive way.
It's not a common phrase. Maybe it could mean 'told all of my little sister's stories' in a rather strange way. But without more context, it's really hard to be sure.
Another possibility is that it's a misphrasing. It could be that your friend helped you out in a really big way, like when you were in a tough situation, perhaps at school or work. Your friend came to your rescue and did so much for you that it was as if they 'ate up' all the problems for you, making the situation better.
We should firmly oppose it. Report it if possible to relevant platforms or authorities so that they can take measures to prevent the spread of such inappropriate content. And also, make it clear that this is not acceptable behavior in a civilized society.
On the other hand, it might be that your friend took over something that was yours in a rather forceful way. Like if you had an idea for a party or an event, and your friend took that idea and ran with it, making it their own and leaving you feeling like you'd been pushed aside or 'eaten out' of your own plan.
Suppose 'ate out' here is a kind of slangy way of saying 'exhausted'. For instance, 'After that long family gathering, I ate out my little sister stories, everyone had heard all about her recent escapades.' This shows that you've told all the stories you had about your sister so much that there are no more to tell at that moment.
Well, first of all, the phrase is really odd and not in line with good taste. It might be a creative but misdirected way of saying they are sharing stories about their mother that they think are interesting in a wrong sense. However, we should uphold respect for family members and not use such inappropriate language or concepts.
