B is for Broken English

Is it just me, or has our new generation of growing children
accomplished the task of recreating what should be PROPER English.
Now I know it is only natural that in all cities there is to be some "slang".
For those of you who don't know what slang is,
here is a definition from www.urbandictionary.com:

Slang - slang is the continual and ever-changing use and definition of  words in informal conversation, often using references as a means of comparison or showing likeness. some modern slang has endured over the decades since its inception (i.e. cool) and some will only last a few years before being rendered obsolete or outdated (i.e. bling bling). slang can be born from any number of situations or ideas (the word slang itself has come to represent selling, especially of illegal drugs), and can be blunt or riddled with metaphor, and often quite profound.    I found it interesting that if you browse this website, you can find just about every slang word out there and it's many meanings. I feel as if we are self destructing with each generation that passes us by. Research has shown that we only use about 10% of our brains. But if we keep combining internet slang and street slang, who says we will not even have that 10% left we are holding on to? If we keep going at the pace we are going at now, we will be just like the people in this movie?
