I have never heard of this slang. I have seen and heard of other slang but nothing like this. I also do not like to hang around people whom talk like that with slang words. Because I will catch on.
My 24 year old friend talks like that all in slag and I can't understand him sometimes.

BBB work on your "slang" and street names for drugs, etc. It'll help you when you're a cop (oh, and swear a lot! but only with the appropriate clientel)
Just before I went on my leave one of my sources forgot I was a cop and wanted me to score heroin with him. I had to remind him I was a cop and then the dumbass wanted me to call his dial-a-doper for him. lol
