Clic

A close group, a network of friends who from the beginning are never part of any other group. They only talk to those inside the clic, hangout with the clic, etc.
Yes, there can be leaders among the clics, which then the rest of the group are called followers.
This term is probably better use in middle school, as high schoolers tend to grow away from clics, and actually talk to other people and be a real person.

A woman who is in a clic and strips off her clothes to increase her reputation. In other words to be thought of as really hot. Because she has the guts to do it and to show that she has a steaming hot body. By doing this she often becomes the leader of the clic and can get the hunkest guys.
clic striping is sometimes done at a party, secluded hang out ect.
