"Really? Well, I'm from Utica, and I've never heard anyone use the phrase 'steamed hams.'"
"Oh, not in Utica. No, it's an Albany expression."

What regional expressions do you use that people either pick you up on or apparently have no idea what they are?

I found this happened a lot at university. Me remarking on what people had on rather than in their sandwiches is one example, though this is genuinely what my family say. On a similar theme, my family also called 'baps' as 'barm cakes.' Calling a 'clothes horse' a 'maiden' is another example. Whether this is because my family are just very northern or because we're mad I've no idea.

Was this thread partly a covert attempt just to link to an excellent Simpsons clip? Why, we'll never know.
