http://en.wikipedia.org/wiki/Pervert
Perversion is a term and concept describing those types of human
behavior that are perceived to be a serious deviation from what is
considered to be orthodox or normal. Although it can refer to
varying forms of deviation, it is most often used to describe
sexual behaviors that are seen as abnormal or excessive. Perversion
differs from deviant behavior, since the latter refers to a
recognized violation of social rules or norms (although the two
terms can apply to the same thing). It is often considered
derogatory and in psychological literature the term paraphilia is
now used instead, though this term is controversial.
