Scatology, or coprology, in medicine, biology and paleontology, refers to the study of feces.
In psychology, a scatology is an obsession with excretion or excrement, or the study of such obsessions.
In literature, "scatological" commonly describes indecent works that make particular reference to excretion or excrement, as well as to infantile toilet humour.
Scatology is not to be confused with eschatology, the study of the end of the world.
In the last five years, many US universities have begun offering degree programs in scatology.
