<human>: So this happened when I was about 13. I have older and younger brothers so we knew all of the "Dirty" words by now. Even my 7 year old brother. 

So I'm walking my dog with my youngest brother (7 years old). He is very small, so he looks like he is around 5 years. There is this couple who had to be around 30 years old walking in the opposite direction from us. They obviously knew we were there, because it's a very narrow path and we were walking right toward each other. 

So they are having a conversation, and right when they pass us the man says something about their "Fucking dog." I thought this was extremely inappropriate to say in front of a 7 year old, but I did nothing about it. However, my brother had a different idea. So right after he says that, my brother stops and says, "ViridisLeo, what does Fucking mean?" I knew what he was up to, so I decided to play along. "Don't say that!" I said, nodding my head so he would keep it going. Then he said "Really? FUCKING FUCKING FUCKING!!! FUCKING FUCKING FUCK!" While trying to hold back laughter, I shoot this couple, who are obviously watching us, the meanest look a 13 year old can give. They don't even apologize, they just quickly walk away with their heads down.

Can you provide a brief overview of the text?
<bot>: Stupid couple says "Fucking" in front of my 7 year old brother, he pretends he doesn't know what that means and shouts it very loudly. Makes the couple feel like shit.
