I am a fan of hats and own a number of them. One of my collection is what is commonly called a "flat cap," though it has many names. Seeing me wearing it one day, my father told me that his father always used to call this style of hat a "go-to-hell hat."
I didn't know whether this was idiosyncratic or a common term but I didn't think much of it until I wore it to work one day. A coworker commented on the hat and I mentioned my grandfather's appellation and he, rather surprised, claimed that his grandfather had used the same term. Given that my grandfather lived in western Kansas his whole life, and his grandfather (as far as I know) lived in central Missouri, and neither knew the other, I feel like it would be a staggering coincidence if both men came up with the same odd name.
So, is the term "go-to-hell hat" in common usage? Is it specific to the Midwest?
