I thought you were talking about the kid and the TV show

Yeah, I can only imagine how the language kids use these days must be hard on language teachers.
I teach reading and writing to children in the Bronx. As one would imagine, I come across a lot that is not Standard English. It used to be primarily AAVE, but recently there has been an influx of other unique language variations related to the number of children for whom English is a second language. There is a pretty simple solution to the issue: code-switching. Children need to learn when certain language is appropriate and when it is not. Now, the fact that language is situation-appropriate has nothing to do with the inherent value of the language. AAVE, for example, is, in many ways, more efficient than is Standard English, it has a consistant grammar, etc, and so is by all measures of language, just as "good" as Standard English; in our society, however, Standard English is considered appropriate in business and academia, so that's what my students need to learn in school.
As long as teachers make it clear that text speak and other forms of slang are inappropriate in certain kinds of writing, and ensure that their students are exposed to Standard English, then there shouldn't be a problem.
