Put a hole in someone's body with a bow and they'll become destitute. You put a hole in them. They can't work. They can't take care of their house or their kids. They've lost it all.
You see this destitute person and decide to give them a cucumber (きゅう). They don't even remember that they're supposed to eat those, so they shove it in the hole you made with your bow.
