i use it .. and like it cause it adds flavor to conversation and comes out naturally .. like there's a new measure of easiness in the conversation.. depending on who i'm talking to and how familiar i am with them .. yet only with those who also use that lingo ofcourse..
however, i dont think its restricted to teenagers at all.. just depends on your experience, background and environment .. its quite related to hip-hop culture, rap, breakdance .. all of which i was/still involved in.
