A mammalian organism (a member of the vertebrates within the class Mammalia, a clade of endothermic amniotes distinguished from reptiles by the possession of a neocortex, hair, three middle ear bones, and mammary glands.) with whom it is typical to be identified as “male” (a person bearing an X and Y chromosome pair in the cell nuclei and normally having a penis, scrotum, and testicles) and out of the many modern social classes, are usually in the lowest classes. These organisms have been known to find extreme sexual pleasure and become aroused (i.e. their genitalia expands to a much larger size) whenever they begin watching a series of hand drawn (or computer generated) frames of animation (originating from the island nation of Japan) played at a high rate that creates the illusion of motion. These are watched on an electronic device which interprets and displays these frames as individual pixels. Because of this, the fellow mammalians in the higher classes look down upon these individuals and are called upon by a common term used to describe these individuals who are sexually aroused by these creations of Japanese origin.
