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.
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.
Perhaps it's part of a fictional or horror story. In horror, there are often concepts that defy normal morality and this could be one such extreme concept where a character has done something unthinkable like actually eating a friend, which would be a very dark and gory plot point.
Well, it might be a sign of a psychological breakdown in the narrator of the story. Eating a friend is an extremely abnormal act, so it could imply that the person has lost their grip on reality and normal social and moral boundaries.
Once, me and my friend decided to go camping. We found a beautiful spot near a lake. We set up our tent and then went fishing. I caught a really big fish, but my friend was better at making a fire. We cooked the fish over the fire and told spooky stories at night. It was an amazing adventure.
Well, if it's a horror story, it might be about a deranged man with a cannibalistic urge who targeted someone's son. It could be set in a spooky, isolated place like an old mansion or a desolate forest.
One time, my best friend and I got lost in a big city while on a shopping spree. We had been so distracted by all the stores and shiny things that we didn't pay attention to where we were going. Instead of panicking, we started laughing. We used our phones to find our way back, but not before stopping at a little café we discovered during our 'lost adventure'. We sat there, sipping coffee, and realized that getting lost together was actually a really fun experience that brought us closer.
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.
Well, once I had a strange friend named Tom. He always wore mismatched clothes. One day, he showed up at school with one red sock and one blue sock. But he didn't care at all. He was also really into collecting old keys for no apparent reason. He had a whole box full of them.
My friend Jack loves animals. He once found an injured puppy on the street. He took it to the vet immediately. After the puppy recovered, Jack couldn't find its owner, so he decided to keep it. Now, that puppy is a beloved member of his family and they are always together, going on walks and having fun.
