What is an exaggeration often used to create humor?

An exaggeration often used to create humor is called hyperbole. It's a figure of speech that uses extreme exaggeration to emphasize a point or create a humorous effect.

Here are some examples of hyperbole:

* "I'm so hungry I could eat a horse!" - This obviously isn't literally true, but it emphasizes the speaker's hunger.

* "I told you a million times!" - This overstates the number of times something was said to create a humorous effect.

* "My backpack weighs a ton!" - This exaggerates the weight of the backpack to emphasize its heaviness.

Hyperbole is often used in comedy, stand-up routines, and everyday conversation to create a lighthearted and entertaining tone.
