Scots chased the French out of Western Pennsylvania, and more than a few of them settled here, along with the Irish, mostly Protestant, but not entirely. (Pittsburgh's first Catholic church was named St. Patrick's. It's still in operation.) So, we say redd up for tidy up, and a neb is an inquisitive person. To be inquisitive is to be nebby. In Scots dialect, I understand, a neb is a nose.
Thorns are called jaggers here. Rubber bands are gum bands. Baby chickens are peeps. Yinz is the plural of you. The clerk at McCrory's told me and my friend Ann, when we bought a very brief red nighty with fringe for a friend who was getting married, "Yinz is really evil."
Low class Pittsburghers are called yinzers.
