No, it's not a common expression. It's rather an unusual and specific way of putting it. Usually, we might say something like'mom sharing my friends' stories' instead.
If we break it down, 'flashing' has the idea of something being shown briefly or suddenly. So'mom flashing my friends stories' could imply that your mom is sporadically bringing up and telling the stories of your friends. It might be that she finds these stories interesting or relevant in the context she's in, like when she wants to make a point in a conversation or just share some interesting tales she's heard about your friends.
A 'flashing my mom story' could be the instance where I dashed in front of her to show off my new dance moves that I had just learned. I was so excited to share it with her, and she watched with amusement and love in her eyes, clapping along as I showed her my newfound skill.
Another way is to create a photo or video montage related to the stories. For example, if your story involves a special event, include pictures from that day and add captions explaining the story. Then, show it to your mom. It will be a very visual and engaging way to share.
Here's a story that happened during a school project. My son and his friends were grouped together to build a model of a historical monument. At first, they had different ideas on how to go about it. But they soon learned to work together, listened to each other's suggestions, and in the end, they created an amazing model. It was a great example of teamwork and friendship.
Begin with a question related to the story. For instance, if it's a story about a bike race they had, you could start with 'Have you ever wondered what it's like to be in a really intense bike race? Well, my son and his friends found out.' This grabs the listeners' attention and makes them curious about the story.
Another positive story could be that the wife has just completed a fitness journey and is now in great shape. She shares with her friends how she achieved this, like her exercise routine and healthy eating habits. It can be an inspiration for her friends to also pursue a healthier lifestyle. In this case, she is 'flashing' her positive achievements to her friends in a good way.
One 'flashing mom story' could be about a mom who quickly flashed a big smile to her child during a school play, giving the child instant confidence. Another might be a mom who, in a rush, flashed her homemade cookies to the neighborhood kids through the window to entice them over.
Perhaps'mom flashing stories' could also be about moms who have a moment of great inspiration. Like a mom who has been struggling to get her kids interested in reading. Then, in a flash of inspiration, she creates a little home library corner with fun decorations and cozy seating. This makes the kids excited to pick up books and start reading more often.
