What is a peppa?

A peppa is an Australian slang term for a girl between the ages of 14 and 15, often used in a derogatory way. The word is derived from the British children's television program Peppa Pig, in which the main character is a young pig who is seen as being naive and annoying by many adults. In Australia, the term is often used to describe girls who are seen as being similar to Peppa Pig in terms of their personality or appearance.
