Here's a simple explanation:
* Hyperbole: A figure of speech that uses extreme exaggeration to create emphasis or a humorous effect.
For example:
* "I'm so hungry I could eat a horse!"
* "That movie was so boring, it made me want to pull my hair out!"
* "I told you a million times to clean your room!"
In all of these examples, the exaggeration is clearly not meant to be taken literally, but rather to emphasize the speaker's feeling.
