Young people don't want to let adults in on their conversation

The slang you use gives away your age? Far out! This article leaves one question unanswered: Why would any adult want to talk with today's foul-mouthed, body-pierced, tattooed freaks yutes?

Slang vocabulary, like musical tastes, or physical height, may be one of those things that is more or less fully formed before we exit our teens...

Pamela Munro, a linguist and editor of U.C.L.A Slang 6, defines slang as "language whose use serves to mark the user as belonging to some distinct group within society."

In other words, when your kid is slangin,’ he’s really saying he is different than you — and he likes it that way.

"Anthropologically, kids form themselves," said Munro. "Slang is a kind of code or password if people are trying to show that they are a member of your group."
