A provincial, typically residing in the western half of Pennsylvania (USA), who strongly identifies with the nearby city of Pittsburgh, Pennsylvania, often due to a fervent, pseudo-religious loyalty toward one or more professional sports teams headquartered there. "Yinzers" are so called because they speak a regional dialect of American English featuring the use of "yinz" or "yunz" as the second-person plural pronoun. Yinzers are the subject of a number of stereotypes, some of which they are actively proud and consciously reinforce to strengthen their sense of identity, an example being their use of French fries as a condiment.
Traffic in Pittsburgh is very bad this afternoon; a veritable army of YInzers has descended on the city due to the baseball game.

White trash from Western Pennsylvania, and sometimes even extending into the "inbred" areas of West Virginia.
Extremely dumb, toothless losers that can be found in large masses watching Steeler games. Known to be very filthy and not familiar with simple hygienic practices such as showering and brushing their teeth. Their most prized possessions are their terrible towels, which they would permanently trade in a moment's notice for running water and soap.
"Did you have a good time at the bar last night?"

"Fuck no, the place was crawling with dumb Yinzers wearing meatball-stained Steelers' shirts. I had to leave because of the horrible stench."

White trash coming from Pittsburgh, PA and the surrounding areas in western, PA, eastern, OH, and northeast WV. Very frequently inbred, under educated, and retarded, the yinzer is a simple breed, speaking in a dialect often referred to as "Pittsburghese", characterized by the fictional word, "Yinz". The Yinzer is a willfully ignorant species, fully believing that pittsburgh is the best city in america simply because said yinzer has never been more than 20 miles from pittsburgh.
