Dr. Scott Kiesling is a sociolinguist at the University of Pittsburgh. Recently, he ignited the stage as part of a speaker series called Ignite Pittsburgh, a TED like program designed to spark ideas among its audience members through short, but powerful talks.
His talk featured Pittsburghese, the unique pattern celebrated by Pittsburgh locals (or yinzers). You can see a short blurb about the talk here:
Dr. Kiesling and Dr. Barbara Johnstone (Carnegie Mellon) have been studying this speech for a while. Unique vocabulary words, include: yinz and yinzers, gumbands, nebby, slippy, and redd up. There are many, many more, and these days they are all over the web. It’s worth a few web searches to check some of them out.
