What does your tongue is dragging on the floor mean?

The phrase "your tongue is dragging on the floor" is a figurative expression meaning someone is extremely tired or exhausted.

Here's why:

* Visual imagery: It paints a picture of someone being so tired they can barely keep their head up, as if their tongue is literally dragging on the ground.

* Hyperbole: The statement is an exaggeration, as no one's tongue would actually touch the floor.

* Emphasis: It emphasizes the level of exhaustion the person is experiencing.

Example:

"After working a double shift, I was so exhausted my tongue was dragging on the floor."
