Rio Grande in Ohio is pronounced that way too.
Lackadaisical. I always want to say Lack-sa-daisical.
Me too, and I don’t know why.
I was told by the Greeks in an American Greek restaurant to say hee-ro. Got the impression that the Greek word was the origin for “hero” for sandwich. But looking it up, Wiki tells me that hero for a sub sandwich came into usage decades before gyro sandwiches were known in the US.
There are two words I have to make a conscious effort to pronounce “correctly”
Jewellry
I still slip on occassion and say JEW-luh-ree though I try to say JEW-el-ree. I got on myself about this after Bush was criticized for NOO-cyoo-ler. I became sensitive to similar words I may be mispronouncing (our grade school teacher exorcised FEB-you-ary early so I was good on that one).
Kilometer
I’ve pretty much habitualized KILL-o-mee-ter instead of the more common kill-AW-mit-er.
People may defend kill-AW-mit-er, but that (IMHO) misapplies the measuring device pattern of (for example) thermometer and barometer. No one says kill-AW-grum, or kill-AW-pa-skull, nor is cent-IH-mit-er or mill-IH-mit-er widely used. I like metric prefixes consistent, thank you.
I hate when people say “axe” instead of ask.
Because you’re being lax when you say lackadaisical.
I chopped down the tree with an ask?!?! That doesn’t make any sense.
I thought the Greeks pronounce “gyro” as “hero”. Not so?
You hate the z pronounced /ts/ and the final vowels of standard Italian? 
Did a Tuscan spit in your pasta fazool?
Hate to break it to you, but in most of Italy, dialects and regional languages are giving way to standard Italian, among the younger generations at least. Your relatives in America have probably preserved some dialectal features that are already obsolete back in Italy.
I’m fine with this. I grew up hearing both Sicilian and standard Italian in my family, but when I went to study and learn better for myself, standard Italian is all I could get. If there are any Sicilian language courses, I’ve never found any (Sicilian was taught at DLI back in the WWII era, but that was before I was born.) When I went to Sicily, my cousins in my generation all spoke standard Italian, and it was only my grandparents’ generation I had difficulty understanding. What’s your region?
Try this.
I am the same with “hydrogenated”. Most people seem to pronounce it with the “ro” rhyming with the “do” in “dog”, but I just can’t do that, it just sounds so wrong. We don’t mangle oxygenated or carbonated the same way, so why hydrogenated?
I’ve never met a birder or seen a dictionary that used either of those pronunciations. BYOO-tee-oh is pretty universal.
I recently learned dour should rhyme with tour, not sour, but it just sounds wrong that way.
Well, first of all, the singular is “gyros” (γύρος). I am not Greek, but there are at least two Greek pronunciations of “gyros” that I am aware of. One begins with a palatal glide (the pronunciation that starts with what English speakers would call a “y.”) From my research, that’s the most common or standard one. There are apparently dialect variations where the initial sound is a voiced or voiceless velar fricative. That’s closer to the “h” pronunciation you’re talking about.
Hee. My husband likes to call them “destructions,” which according to him is what usually happens. 
Mine is “Neanderthal.” It’s supposed to be neeander-TALL, but I feel like a big goober saying it that way. Neeander-THALL was good enough for insulting people for most of my life.
Steel mill. It comes out stil mil. I really have to stop and think to pronounce the ee. Of course I grew up less than an hour from Pittsburgh…
Every morning for the past 20 years when I go in the kitchen I’ve asked “Who wants Cat Fud?”
My problem is anything that starts with the prefix “pseudo”. I say Suede-Oh instead of the correct Soo-Doh. (Pseudointellectual indeed.)
When I first moved to the Deep South, I had to learn to pronounce a lot of things based off the local dialect. I have a bunch that I call “Georgiasms” (Like orgasms, with Georgia).
“Houston” is the county I live in - it is not pronounced HEWS-ten, like the place in Texas, but “HOWS-ton”.
There is a place named “Adele” that is not pronounced “uh-DELL” but instead is pronounced “AY-dull” (like edelweiss?).
Another town is “Albany”, which isn’t “ALL-buh-knee” like in NY, but “al-BAN-ee”.
And coming from Colorado, it was very odd that “Pio Nono” wasn’t “PEE-oh NO NO” but “PIE-uh nuh-nuh”
And “theater” isn’t “THEE-ter” but “the-ATE-er”.
Ahhh, the south…
There’s not really anything unique about Georgia in this respect.
For example, Ohio has a lot of odd local pronunciations:
Russia – ROO sha
Delhi – DELL high
Bellefontaine – bell FOUN tain
Rio Grande – RYO grand
I think this kind of thing happens everywhere
Doesn’t make me pronounce them any less “wrong” 
Stragedy - I use it as a combination of strategy and tragedy.
Brefess - Breakfast
Titleist - will always be Tit -leist for me.
I had a friend in university that was famous for his mispronounciations and I still use some of them today. Those I can remember include:
Szechuan - Shway-zen
Carafe - Cara-fay
Pheasant - Peasant
Vegetable - Veggie-table
The funniest argument I ever had was with former drug addled room-mate, who fancied herself an intellect despite not even completing high school (she was too smart for their learning, LOL). She adamantly insisted that the word “pronunciation” was pronounced “pro-nunk-shoo-a- tion.”
This was, in itself hilarious to all but the fact that she didn’t see the irony in it was so funny that we were on the floor of the pub laughing and my sides were sore for a week.
I still chuckle out loud thinking about it now.
