The Descriptive Peanut is a ribald poetic form, originating in The Custom of Shoulders. The rules of the form are applied by poets to produce individual poems which can be recited. The poem is divided into three distinct parts: a septet, a quintain and a line. The Descriptive Peanut is always written from the perspective of the author. Use of consonance is characteristic of the form. Forms of parallelism are common throughout the poem, in that certain lines often contrast underlying meaning and they use the same placement of allusions. Each line has five syllables. Every line of the poem has a terminal caesura.
