The document discusses several youth subcultures or "tribes" in the UK, including:
1) Aspirant Mainstream made up of Rahs and Trendies who are open-minded and freely spend money on fashionable brands and trends influenced by celebrities on social media.
2) Urban tribe draws inspiration from their environment including clubs and social media, with divisions like DIY-ers, Blingers, Get Paid Crew and Trackies, focused on fashion, music and materialism.
3) Alternatives are determined to be different through fashion brands like Converse and focus on defining their interests through friendship groups and online activities rather than mainstream influences.
