Social dialect
From Cyborg Anthropology
"A dialect spoken by a speech community that is socially isolated from others. Social dialects are mostly based on class, ethnicity, gender, age, or particular social situations. The upper class English "public school" way of talking is an example of a social dialect". http://anthro.palomar.edu/tutorials/cglossary.htm
