Debate: School slang

There are some my thoughts about slang/argot. I don’t really know about British slang, so I want to give you some ideas about slang/ argot in general.

One day :) a man with charisma appears (according the L.Gumilev theory about passionation: he is a passionate person (not only in good meaning), he begins to use some broken phrases, his own new words. His charisma unites people with weak will around him. They want to become similar to him, they imitate him, copy his “wrong” words.
Almost always these people are teenagers, cause their will is not strong yet, they can’t recognize smb influence, and they depend on alien opinion. They want to look “their own” in the company, so they use the language of the group.

But sometimes the group, where the argot is moving, can be the group of people joint with common idea (for ex: “futurism” in Russian poetry of the beginning of XX century), or can be the group joint with common condition (for ex: the jails argot: a newcomer doesn’t want to become a “white crow”, so takes the rules of prisons society (argot becomes the defense of him))

The originator can be everything; it depends on people who unite this group. Although, I think, some modern music (for instance Mylene Farmer’s song “f*k them all”, it’s full of scolding words, but it sounds nice :( ), movies, may be sport (when the deal concerns fans), surely drugs have an influence on appearance, development of slang.

The driving force of it is…(my idea) natural people’s wish to feel more comfortable with surroundings. And if someone doesn’t have wisdom not to get under someone’s influence, it will be not really good for him.

So did I get the answer for your question? Give me your opinion for this problem.
