That’s some righteous dyslexia, I’ll say! 
A policeman friend back in West Texas told me his fellow officers all called it a Cocksucker’s Cap due to this one particularly annoying reporter on the police beat always wearing one.
I’ve never heard flat cap before, but I’m fine with it. I’ve called it variously just cap or driving cap. It seems like I’ve heard Gatsby cap somewhere.
It might be worth noting that in the UK, the wearing of flat caps is part of a (usually good-natured humourous) stereotype about ‘northerners’ (which for southerners used to mean anyone north of Watford, Northamptonshire - but this seems to have become confused with Watford, Berkshire, and so now the stereotype may be jokingly applied to anyone north of London).
Northerners in this stereotype are characterised as Yorkshiremen by speech and attitude, proudly poor, owning a whippet, drinking tea, brown ale and bitter, eating black pudding and lard, talking about the moors, or trouble at t’ mill, and wearing a flat cap.
I don’t know that I would have known what to call it, other than a hat. It’s not something I experience enough to have a “normal name” for. I guess I associate them with old men (I think my great grandfather used to wear one or something like it), so maybe I’d call it an “old man hat” if I was trying to differentiate it from other hats for some reason.
Flay rod’s gone out of skew on the treadle?
Scally cap
I’ve always called it an “English cap” or “English driving cap.”
An embarrassment. I’m not sure how you pronounce it, perhaps it is French or Spanish?
I call it the Ecky Thump hat.
No, I don’t, I call it a flat cap, or a cameraman’s hat when worn backwards. Where the definitive example for me is Ben Volpeiere-Pierrot, not SLJ.
I called it a Jackie Stewart racing hat because I saw a photo of him wearing one in a racetrack pit.
This is just a trivia thing I’m wondering if anybody else can relate to: when I was a kid (back in the 1950s) my aunt had a deck of playing cards for something like Old Maid or one of those games where you had to get a matched set of four of the same face to win the game. A lot like Authors, too.
Anyway, there was a character in that set named Toughie Yegg. He was a safe-cracker or burglar or some other type of ne’er-do-well. He had on a broad-striped polo shirt and was wearing one of these caps and a Lone Ranger looking mask (like most cartoon and comic strip shady characters did). That’s the first time I can recall seeing the type of cap we’re discussing. And I think at least one of the Bowery Boys wore one, too.
Just trivia, but does it ring a bell with anybody else?
Guessing Fred Dibnahwould be a good example?
Also, I call it a flat cap or driving cap.
I’ve had a few of them and were referred to as Salt and Peppers or Gatsby Caps.
Pretty much, although the stereotype often also includes a sort of attitude of bitter misery. Fred was quite a joyous man.
You seriously don’t know a single person who wears a hat? I can see six hats from where I’m sitting in the library. They are pretty common.
Oh, there’s number seven.
As contrasted with when Cockneys wear them.
OK, I may be off on the Cockney bit …
Heh. I have a couple of 'em, and am a photographer. Looks better when turned backward than a ballcap. (the bill gets in the way of the camera viewfinder, y’see.)
I’ve only ever heard “flat cap” or “driving cap”. A “newsboy” is entirely different, it’s floppy on the sides, made of several panels coming together at the top and has a button on top, sort of like a collapsed extra-tall ballcap; a flat cap is, well, flat on top (has a top bit and a side bit, fabric-wise) and doesn’t have any extra floof in the sides.
A “Kangol” like Sam Jackson wears is a brand name used generically for a certain style of one-piece felt flat cap (cf. “Stetson” or, if you’re old and from certain parts, “Resistol” as a generic term for cowboy hats.)
Similarly, “tweed cap” is a subset of “flat cap”.
I’ve always called them “Cabdriver hats” or “Gamekeeper hats” - I’ve always associated them with London Black Taxi drivers or, gamekeepers from posh estates.
