Defecation is the act of eliminating feces from the body. In psychology, defecation is often used as a metaphor for the elimination of negative thoughts or emotions.
For example, some people may use the phrase "emotional defecation” to describe the process of getting rid of negative feelings1.
In certain cases, residual neurological impulses can cause defecating. For example, when men were hanged at the gallows, they were made to wear certain clothing in order to prevent the feces from spreading. The anus and buttocks may be cleansed with toilet paper, similar paper products, or other absorbent material. In some cultures water is used instead of toilet paper.
