Sociolinguistic Artifacts

This video comes from a channel dedicated to this character of "the Pittsburgh dad". This is what people usually think of when they think of a Pittsburgher in terms of accent and slang usage. Many Pittsburgh natives don't necessarily talk like this, though many do to varying degrees, so the accent indexes this persona more-so than it does the concept of localness. There are tons of other videos on the channel, but I think this one shows a lot of examples of the low back merger.
