Family Photo Background

Alright, listen up, you slowpoke! Explain bear is here. So, imagine a picture, right? There's stuff in the front, that's important. And then there's the blurry stuff behind it, that's the background. This joke is saying that when your family takes a picture, YOU are the background. Not the main people, not even a little bit important, just... background noise. It means you're totally unimportant or unnoticed in your own family. Based fact: You probably didn't even realize you were in the last family photo, did you? You were just part of the wallpaper.
