Something you own but never use. It’s like having a toaster in your closet and not knowing what it is.

I got a new phone but still use my old one. That new phone is a dusty.

I bought a bike last year and it’s still in the box. That’s a dusty.

My mom bought a blender and it sits in the cabinet collecting dust. That’s a dusty.
