I think it’s becoming acceptable (probably due to so many people like us pronouncing it that way) but the rhymes-with-bluer pronunciation is clearly the primary one.
The primary pronunciation is sooPERfloous.
soo-PER-floo-us, not SOO-per-FLOO-us.
Ahh you meant which is the accented syllable. Yes, the really arrogant bastard was right 
Maybe because English is not my native tongue, I usually avoid trying to pronounce words that I have only seen written, although I can’t think of any at the moment.
I think it’s ok for people to mispronounce some word that they only use very rarely. But what always amazed me is when people constantly use a word but don’t bother to learn how to pronounce it. Like WoW players who in vent mispronounce “melee” in various very inventive ways. But they can tell you what the difference between a mace and morning-star is.
I always mention victuals in these threads. (Properly pronounced “vittles.”)
Unless I think about it, Strategy will invariably come out as Stragedy.
I blame Bugs Bunny.
I still say carmel for caramel, and probabyl always will. I friend says many weird words like cyrogenic (for cryogenic).
I can’t not see “Hyundai” as “hi-un-die.”
“Lien” is “lee-en.”
For the longest time I thought “expletive” was “ex-pel-tive.” I figured that one out tho.
My friend carved Cthulhu in his pumpkin this year and none of us at the pumpkin carving party had any idea how to pronounce it. We’d never actually heard it pronounced before, just written.
I have a couple of friends who pronounce it like that and it drives me crazy. (They’re brothers which I suppose explains the shared pronunciation.) It wouldn’t be too bad, except that I play role playing games with them so the word comes up fairly often.
Same here. I blame Captain Planet.
For me, I always have trouble with “rural”. The two “R” sounds always blur together for me and I have to be careful to enunciate the first syllable or I sound like I’m saying “rull”. The word “horror” similarly (and embarrassingly) sounds like “whore” if I’m not careful.
I cannot for the life of me properly pronounce that headache medicine that you shouldn’t take when you’ve been drinking. You know…
Acetamuna…
Acitiminifina…
Acinnamoonafun…
Tylenol.
Here’s another one, that I blame on my midwestern grandparents. Both my mother and I grew up thinking that bagel rhyming with haggle was a legitimate alternate prononuciation. Apparently not, only BAYgle is correct.
I also have to think hard in order to not say “nucular.” I did think for a long time that Schroeder’s favorite composer was pronounced BEETH (like teeth) - oven (like where you bake cakes).
Soooo…superfluous.
sue-per-flu-ous, right? The “soo” makes me sound it out like my long, drawn out “so” at the start of this. I have always been a pretty good speller/pronouncer of words, but some “foreign” words can always be tricky and I do not mind mispronouncing them until I’m corrected. I figure that since It’s not my main language, I’m allowed a little leeway.
Nowadays though it seems new words pop up everywhere. “Meme” I always pronounced as “me-me” until I read this thread. That got me to thinkin’ about how the “younger” generation “tweaks” common words and usage until it almost becomes a new language (See just about anything on Reddit). I’m a firm believer that language is always changing, and I support that. I’m not usually a “grammar nazi” because sometimes people make honest mistakes that I feel do not need to be pointed out and have them criticized. In these cases I use my reading comprehension ability and some common sense to figure out what people are trying to say (or type, as it were).
On the other hand, some words just make me mad. For instance, “Staycation”, I pronounce it as “Don’t-Fuckin’-Say-That-Word”. Maybe that makes me a bit of a hypocrite, but I’m ok with that. 
I always pronounced ‘magenta’ as ‘mag-nee-ta’; sort of like Magneto’s little sister. 
Fortunately, my housemate does the same thing, so in this house, it’s the right way to say it, dagnammit!
Acetaminophen: a-SEAT-uh-MIN-uh-fin.
Apparently, Cthulhu is pronounced as if there were an uh between the C and the th. So it’s kuh-THOO-loo.
And I had no idea about dour. But now I do.
My main gripe is with English-ized foreign words. Especially from languages where they do not use a roman alphabet. For example: feng shui. The original Chinese characters bear no resemblance to the English transliterated letters, so why not spell it like it’s supposed to be pronounced, fung-shway?
It’s feng shui in the pinyin system, or really, fēng shuǐ.
I thought mishap was pronounced “mi-SHAP” for the longest time.
Meme tripped me up too. It’s still hard for me to think of it as “Meem.”
For the longest time I thought “Hirsute” had an extra “i” in it was was saying “her-SWEET”. I was describing someone to my friend as “hirsuite” and she stared at me a minute and said "I think you mean “hirsute?” I didn’t believe it and we actually got out the dictionary to check. Man did I feel dumb!
Grocery–I have a bad habit of saying “gro-shree” when most dictionaries prefer something closer to “grossery”.
Hegemony–I assumed it was “HEDGE-uh-mo-nee”, but “he-JEM-uh-nee” is listed first in the dictionary I consulted, and that’s the way I’ve heard it more often.
Elicit–For years, I mentally pronounced it “ee-LIKT”, not bothering to notice the second I. :o
Chimera–I heard it in biology class as “ky-MEER-uh”, but I was briefly floored when I heard someone else pronounce it “shimmer-uh”. The first pronunciation was correct, thankfully.
The majority of “wh-” words are really supposed to begin with a /hw-/ sound, and I know someone who makes a point of pronouncing it that way, but I think it requires a bit of effort and am a big fan of the “wine-whine” merger.
I used to prononce epitome as “epi-tome.” To be far, it kind of looked right!
The one I can never get is bagel.
If I think it IPA, begl, I can pronounce it just fine. But about 75% of the time during normal speech it’ll come out as bɶgl. Bag (as in shopping bag) + el. Much to everyone’s amusement but mine. I better switch over to the correct pronunciation somehow as I just started working at Panera. :smack:
If it’s any consolation, while I never mispronounced it I knew the meaning and pronunciation of the vocal “segue” for years. But I didn’t connect it to the written word “segue” until I was a sophomore in college. My good friend and roommate teased me mercilessly about this ("I thought it was some crazy written word, “seh-goo”!)
