Almost: woost-uh-shuh
The correct pronunciation is helpfully demonstrated in this well-known instructional video:
Whatsthisheresauce
More correctly pronounced “That stuff nobody I know uses that I’ve never seen being bought.”
I agree. While I’m old enough to have routinely used the term “core dump” when it really referred to physical ferrite core memory, these days even I, the ancient one, am more likely to use a term like “memory dump”.
I was instinctively about to say that core memory isn’t quite that old, but in retrospect the reality is that I’m that old, so it seems relatively recent. But the university where I studied and later worked had a PDP-10 timesharing mainframe that used entirely core memory, IIRC each 16K (or possibly 32K) of 36-bit words taking up an entire cabinet the size of a wide commercial refrigerator, so that a PDP-10 with 256K would require a row of at least 8 such cabinets. My own department had a variety of DEC minicomputers, the newest of which – the PDP-11 – represented the transition from core to semiconductor memory that began in the early to mid-70s. It was interesting because at the time, semiconductor memory was faster but a lot more expensive than core, and so was considered an optional feature for high performance, where the lower physical memory addresses where the OS resided would be mapped to semiconductor memory (either bipolar TTL or MOS) and the rest would be core.
Ahem! And here I thought we had you educated about Caesars! Most would consider a dash or two of Worcestershire to be among the important ingredients in a Caesar, and possibly even in that American abomination, the Bloody Mary. 
That said, since I make my Caesars from a premix, and never use Worcestershire for anything else, it’s in fact true that for many years now I haven’t bought the stuff. But no good Canadian bartender would ever be without it!
Truth be told, I did in fact buy a bottle for the great Caesar experiment. Which bottle was used successfully for that project (thank you again!) and other than further Caesars has seen no other use.
It was however the first bottle I’d bought in my adult life. And I’ve been buying my own groceries for nigh onto 45 years now. Yet somehow the vile fluid is always on the shelf at the store. 'Tis a great mystery.
I think the traditional paper-bag-as-label is intended to disguise the fact the bottles actually date from the 1950s; every now and then when they get too shop-worn the old paper bag is torn off and a new one is applied at the store. 
I don’t think I’ve grilled anything* without a few dashes of Wüst’-a-sher Sauce. It’s wonderful.
*Except salmon. Grill that with just garlic, salt and lemon.
I’m pretty much on board with you. Burgers, especially, get a dash of Worcestershire sauce while being made. Chicken gets marinated in a marinade containing, among other things, Worcestershire sauce. Skirt steak (my absolute favorite for grilling) gets marinated in (among other things) Worcestershire sauce.
I’ve found that it doesn’t work so well as an ingredient in a marinade for pork chops, though.
Salmon and swordfish get nothing but lemon juice, salt and pepper.
I love sea bass but quite honestly, I’d likely never have tried it if it had not been renamed! “Patagonian toothfish” sounds like a prehistoric sea monster from the Jurassic era.

It goes on just about any meat that I cook and a lot of sauces I make. I put it in deviled eggs and tartar sauce. It’s one of those things I have to have in the kitchen; a staple like salt and pepper.
Hell, I go through a bottle of Worcestershire and a bottle of Angostura a year, easily. Myriad uses in the kitchen/bar for both.
Except Caesars. Those things are fucking vile. 
Forget not the elegantly shaped, delicious, and oh so popular Slimehead … er … umm … Orange Roughy. I shit thee not.
I was introduced to Angostura bitters-and-7up as a cure for an upset stomach some thirty-two years ago. It has been so successful that I now advocate the remedy with the zeal of a missionary.
Can I be annoyed by a primary product name, not the alternate?
Hoverboards. Those electric skateboards that don’t hover. Are they called that just to profit off a popular movie made 30 years ago? Or were they invented by the dental industry to goose the demand for implants? So when Elon Musk invents a true hoverboard, are the manufacturers of ersatz hoverboards going to say, “Nuh-uh, we own that trademark” (even though ours have wheels)?
7-Up was always our nausea medicine when I was a kid. I can’t drink it as an ordinary drink anymore. It’s like hot tea with milk and sugar. That’s what we got if we were sick without nausea. I always call it “sick tea.”
I live in a suburb of the capital of the United States.
A couple of years back, newscasters etc. began to refer to the area as the DMV. (DC, Maryland and Virginia).
No, thank you, I do not live in the Department of Motor Vehicles.
(edit: shoulda read the thread - I am not the only one with that gripe!)
When I was working in a casino one morning about 8 a regular was a bit hung over and complaining about a techy stomach. I asked the bartender for bitters and still water “for a hangover belly.” He put in about three dashes and a couple ice cubes to cool it just a bit. Perked the customer right up.
See the Ghostbusters cartoon, which had to be called “The Real Ghostbusters” since a cartoon had already been created as a spin-off of the little-known 70s live-action children’s show, The Ghost Busters.
Oh and 
the Ghostbusters cartoon…
…just happened to premiere 5 days before…
Total coincidence of course. Everyone tosses out an animated adaptation of a short-lived children’s TV show 11 years afterward. That’s just what you do.
