:::Animal roleplay is also known as 'bestiality' in its archaic definition, "the stupid brutal quality of a beast", as applied to a human (as opposed to anthropomorphism applied to an animal, thus giving it human qualities). 'Bestiality' has been used to refer to 'sexual activity with animals', this terminology is perhaps wearing off a little with people naming it 'zoophilia', instead, since 'zoophilia' sounds less pejorative, in the sense that the animal isn't derogatively classed as a beast. The fetish of animal roleplay may also be considered reverse anthropomorphism, something notable in furry yiff role-players whom also do this (by fursuiting or online interactive virtual reality or MUCKs (i.e. like those in Second Life). The interest in yiff, sexual human-animal roleplay and bestiality, etc, may be collectively caused by mixed fetishes and/or paraphilias towards animal traits or simple, although scientists are now debating over whether the sexual attraction to animal traits is a real sexuality or not, and if it is, on re-thinking sexuality altogether, as written in a recent article by the Scientific American.
