A roman à clef or roman à clé (French for "novel with a key") is a novel describing real life, behind a façade of fiction. The 'key' is usually a famous figure or, in some cases, the author.
"The entire peice that concludes with "as a wife has a cow a love story"--not only its final section--is a love story. The conclusion of lovemaking is a cow; the conclusion of verbal union is a book. Cow and book are sexual and artistic creations, intimately related. A Book Concluding With As A Wife Has A Cow A Love Story (1923) is a portrait of [Alice B.] Toklas.

A rose is a rose is a rose is a rose.
And then later made that into a ring I made poetry and what did I do I caressed completely caressed and addressed a noun." (Lectures in America)
