I don't bother with slang anymore, it takes way too much hard work to figure out what it means, and then, when you get accustomed to saying it, it's totally played out. Only times I usually get into contact with it these days is in some rap, and sometimes I have to look the stupid words up at stupid sites like:
http://www.urbandictionary.com/
http://www.ocf.berkeley.edu/~wrader/slang/
http://www.thablingster.com/dictionary.html
http://www.cox-internet.com/dabster/slang.htm
Standard English is sufficient enough for me.
