I was traveling earlier this week for work out of state and asked someone where I could find a bubbler. I got several strange looks the more people I asked. I never knew "bubbler" was a local New England expression (apparently). When I finally described what I was looking for, the woman said, "Oh - you mean a water fountain!" (For the record, a water fountain to me are those things you throw coins in to make a wish).
And I saw an episode of "Say Yes to the Dress - Atlanta" and learned that in the South if someone says something is "lovely", it's their polite way of saying they don't like it. I didn't know that
What are some local idioms that you like or have encountered? Of course being from Boston, one of my favorites has to be "WICKED!" (another word for awesome). I knew "wicked" was a local thing to Boston. But I had no idea about "bubbler".
