Sling Shot

The following happened with an 8 year old at work today-

After he was overheard telling another child that he could see her underwear and I shook my head at him, to let him know that he shouldn't be saying this. He says to me, rather loudly, from across the room, "What? At home when my mom bends over and we see her underwear, we tell her that we can see her sling shot!"

I'm guessing she doesn't wear briefs.
