Is there certain rules of a clique group that you need to follow or it's usually broken rules?

I feel like the only rules you tend to find are the general rule an of life, most of which you can sum up as ‘Don’t be an asshole’

Unspoken rules

I am not into cliques

You must shun the designated shunees.

Not really. Most of my friends are artistic and creative. Many are also politically progressive, which seems to go with that. 🙂
