Citizen?

Isn't city-shect a slur for citizen?

Not really. Its 'city sect'. Like a religious sect. A sect in the organizational sense.

It's basically used by Alices as a way to describe something cool or amazing. Basically anything they like.

City-sect is city-sect. If you don't understand easy, you're a country bumpkin and there's nothing we can do to help you understand.
