Pittsburghese comes from Pennsylvania Dutch, a descendent of Dutch settlers back in da day. Every time I hear it I get nostalgic; as the years go by I've lost my fluency.
The infinite variations on American English fascinate me. As I searched youtube for just the right illustration of Pittsburghese, I also found a beautiful description of Gullah english:

And of course there's Cajun, Amish, Appalachian, it just goes on and on. I think I missed my true calling as a linguist. I would have been cunning indeed.
LMAO! That was so wrong. LOL! My mother-in-law is Pennsylvania Dutch so I'm quite familiar with many PD terms.
Chicagoans also have their own unique way of speaking/slang. A couple examples: Jewel/Osco is a large grocery store chain here, you will hear some people say they are going to "da jewels". Also "You guys" refers to speaking to anyone more than a group of two, be they male or female. "You guys wanna get some pizza?" Those with a *heavy* Chicago accent will say, "Youz guys".
