I thought i was good in street language. The amazing thing is that the evolution of language in the street world is like the life of a housefly; seven days and your are a fully blown entity. That's how first the langauage grows in these areas. I felt like an old folk, a nineteen sixties when i realized that i am almost being blocked out from the street language. Being with teens from the Ghetto can make you understand better what am talking about. Disappear from such contexts, forget the mastery of the street language!
