From working in a youth centre, it seems like sterotypes arent as big a thing as they used to be and have all kind of blended together. The only term I ever hear along those kind of lines is road man which the kids use as a general term for anyone who breaks the law or is in a gang (im in london, the definitions could probably alter slightly outside of the city). Nowadays they seem to find identity and categorisation in their sexual orientation, skin colour or cultural heritage, and nuerodivergence instead of stereotypes.

Apparently 'chav' stands for Council house and violence, i didnt know this until recently.
