Hyperbole: exaggerated statements or claims not meant to be taken literally.
Examples:
I've told you to clean your room a million times!
(million exaggerated)
It was so cold, I saw polar bears wearing hats and jackets.
(cold being exaggerated)
She's so dumb, she thinks Taco Bell is a Mexican phone company.
(her dumbness exaggerated)
hope that helps :)
