I grew up in PA, the son of a West Virginia Farmer and a PA farmer. Its a miracle I don't say warsh on laundry day.
Some other PA-isms that you may have heard:
Picksbergh. Its a city in western PA
Dahntahn. That is the urban section of an esablished city
Sannich. Typically meat between two pieces of bread.
Per-mannys. A dahntahn Picksbergh restaurant (Primanti's) that sells sanniches... or sannich's as the case may be.
Fer-Rihw? Meaning; are you kidding? Most of us know it as "for real?"
Shneew. This was what my neighbor called her daughter. Her name was spelled Chenille.
'n-att. A contraction of "and that." For instance, "you wanna go dahntahn to per-mannys 'n get a sannich 'n-att?"
'yinz. evidently a contraction of you and ins. For instance, "yinz wanna go dahntahn to..." I actually heard a "yall'ins" once.
Uptahn. Going to the bars up in town.
Vijzzal. What you see with your eyes. As in, "vijzzal arts"
Arn City. Since the Picksburgh is known for its production of the metal Iron... or Arn. Its also the name of Picksburgh's product shown in the next example.
Ber. Its a foamy brewed beverage. Another example of this beverage is Miwwer Lite.
