A cult in the Naperville area which consists of high school students who are against partying, drinking, smoking, or drugs of any sort. It is widely popular for party-goers to chant "fuck jkb" at parties. It is also rumored that not a single person from the organization has been laid.

Hey, are you going to that party tonight? Everyone is supposed to be there
