What is the term for an author's mocking imitation of another author's work?

Globular Martian, Ha ha!! probably good book!! I should probably read it!! I love memes and parodies!! a lot of the times I try so hard not to laugh but I can't it is just to funny!

I liked lord of the flings

The best Parody I've ever read was Bored of the Rings. It's very cleverly written.
