Hyperbole means an intentional and obvious exaggeration used for emphasis or effect. It is a literary device or figure of speech that uses extreme exaggeration to create strong emphasis, express emotions like anger or humor, or make a point more vivid. Hyperboles are not meant to be taken literally and often involve exaggerated claims such as "I've told you a million times" or "I'm so hungry I could eat a horse" to convey strong feelings or dramatic effect.
