Timothy Jay argues, citing Leach, that the use of animal epithets as insults is partly down to taboos on eating pets or unfamiliar wild animals, and partly down to our stereotypes of animals' habits, such as that pigs in popular culture "are dirty, fat, and eat filth". Jay further cites Sigmund Freud's view that obscenities that name animals, such as cow, cock, dog, pig, and bitch, gain their power by reducing people to animals.[10][11]
