Hyperbole is when someone stretches the truth to make a point. It's like a big fat fish story. If your friend tells you, "I caught a fish that was as big as a whale," that's hyperbole. The fish probably wasn't that big, but your friend wants to emphasize how impressive the catch was. Basically, hyperbole is when you exaggerate something to make it sound more exciting or important. It's like a fun way of being dramatic.
