Self-parody
A self-parody is a parody of oneself or one's own work. As an artist accomplishes it by imitating their own characteristics, a self-parody is potentially difficult to distinguish from especially characteristic productions. Self-parody may be used to parody someone else's characteristics, or lacking, by overemphasizing and/or exaggerate one's own. Overemphasis can be made for the prevailing attitude in their life's work, social group, lifestyle and subculture. Including lines and points made by others or by the recipient of the self-parody directing it to a parody of someone else which that other person is likely to remember and can't de-emphasize without frustration.
Sometimes critics use the word figuratively to indicate that the artist's style and preoccupations appear as strongly (and perhaps as ineptly) in some work as they would in a parody. Such works may result from habit, self-indulgence, or an effort to please an audience by providing something familiar. An example from Paul Johnson writing about Ernest Hemingway:
