High school cliques are social groups formed by students who share similar interests, values, or backgrounds. These groups often include categories like jocks, nerds, goths, and popular kids. Members of a clique typically spend time together, influencing each other's behaviors and social interactions. Cliques can provide a sense of belonging and support, but they may also lead to exclusion or bullying of those outside the group. The dynamics within cliques can change over time, as students grow and their interests evolve, leading to new friendships and shifting social hierarchies.
