I only find that obnoxious when they come of as "one-upping" the other person. Maybe I'm wrong and people secretly think I'm obnoxious, but I think it's a good thing to quickly mention something like "my mom Y" to show your familiarity with a topic, so the other person knows how much detail they need to give when talking about it. Like, if they're explaining what a certain company does in detail, and your mom works there, you should probably let them know before they explain a ton of stuff you already know. I think the key is just to steer the conversation back quickly. If you derail it talking about yourself, steer it back with something like "So how did you like X?"
