What is writing that uses exaggeration or broad humor to poke fun at a serious work called?

The term that describes writing using exaggeration or broad humor to poke fun at a serious work is parody. Parody specifically mimics and exaggerates the style, tone, or content of the original work to highlight its flaws or absurdities in an entertaining way. It often aims to entertain while also providing critique or commentary on the original material, making it a form of artistic expression that can both amuse and provoke thought.

While satire is closely related, it generally refers to a broader genre that critiques societal norms or human vices, not exclusively through humorous imitation. Mockery, though encompassing similar themes of ridicule, often lacks the playful imitation characteristic of parody. Commentary involves discussing or providing opinions on a subject, which may not necessarily involve humor or exaggeration. Thus, parody is the most fitting term for writing that specifically exaggerates serious works for comedic effect.
