parody

Definition from Nolo’s Plain-English Law Dictionary

When an author or artist ridicules a well-known work by imitating it in a comedic way. To the extent that the parodist copies material protected by copyright, the publication may be considered a copyright infringement unless excused by the fair use defense. The key factor for a parody to qualify as fair use is whether the parody is transformative -- it adds something new, with a further purpose or different character altering the copied work with new expression, meaning, or message.
