These people feel they need to prove their ability to make people laugh, and in some instances even cry. By hurting some innocent bystander, these people are becoming negatively popular and part of the in crowd . Their popularity is not real because they are usually just liked by those who in fact like to hurt other people. Those on the other end, those receiving the sarcasm and grief, are not even thought about. Because in the eyes of the person who is making fun of them, they have no friends, nor do they wish to have any.
Teenagers can be the cruelest people in the world.
At my high school, there were such cruel cliques of girls and boys that someone would cry daily. I went to Notre Dame High School. It consisted of fairly wealthy teenagers who thought they were the best. Some were nice to everyone, but there were also groups of people who spent their days making fun of those who were not up to their standards in the popularity department. Whatever it took to make other clique members laugh.
