The term CIS kid (or aleternately CIS people) has gained much momentum as of late among the english speaking adolescents of Denmark. It is used to describe a person of great contempt for his peers merely due to their social or economical status. They are fast to critise everything and everyone around them, however remain indifferent to their own shortcomings.

They are in essence snobs of the worst caliber. Their friendships (if one can call them that) are more often than not superficial, and based on social context.

a place where kids in every class choose to stand out by making complete asses of themselves- this includes drinking/smoking cis or weed in the bathroom, yelling over used catch phrases, Napoleon Dynamite quotes, or by being complete gym rats and tools.
enough said.
