Parody is a form of writing, or other composition, in which an author's style and/or subject matter are imitated in such a way as to make them seem ridiculous. Any distinctive style and any distinctive convention are open to this type of treatment. Some parody is termed "affectionate" — this is when the main intention is to amuse rather than to damage a reputation.
There are various anthologies. Probably the best known collection of parodies by a single person is Max Beerbohm's A Christmas Garland.
