Machine that does nothing
A thing that takes up space but doesn’t work, and it’s so annoying you want to throw it out the window.
My old computer is a machine that does nothing. It crashes every time I open a photo.
This blender is a machine that does nothing. It makes loud noises but won’t blend my smoothie.
That microwave is a machine that does nothing. It’s been sitting there for years. Still doesn’t heat my food.
