I'm from outside (1hr) of philly and didn't immediately recognize "jawn" as written in this article. I moved away about 8 years ago and I think the word has evolved quite a bit. We used to say "juant" which seems close to "joint" as the author notes. "Pass me that juant, where did you get that juant." Haven't heard it with the hard n.

I'm also from outside the city (30 minutes) and recognized it exactly as described in the article. I've never heard it as a replacement for "the shit", though -- go figure.
