Just respondifying to these tantalizations.
I used to have a major problem with the word “hella”. It’s a bay-area-and-north word, that means “very” or “a lot of”.
Is he cute? Dude, he’s hella cute!
Nah, I’m not hungry, I went to the buffet for lunch and had hella chicken.
I’ve made my peace with it in recent years, but I still twitch a little.
Irregardless.
I now have my kids telling people…“You mean anti-dis-non-irregardless?” Just to make their point.
One that I mangled for a long time: massive Christian burial.
(Mass OF Christian burial. Very different. 
)

It was an innocent mistake but my Aunt once said, when discussing a relative of ours with lung cancer, **"…are you kidding, he smokes like a fish!!". **She clearly just confused “smokes like a chimney” with “drinks like a fish”, but the fact that she said it so emphatically to such a large group of people just cracked me up. The best part was that I was the only one to notice, so while I was laughing hysterically, my relatives were looking at me like I was crazy for laughing at lung cancer.
To round things out, here are a few more. Although words and not phrases, they make my spleen hurt whenever I hear them and, therefore, deserve mention.
Pronouncing the word ‘deteriorate’ “detiriate”
Pronouncing the word ‘mischievous’ “mischeevious”
Pronouncing the word ‘espresso’ “expresso”
Pronouncing the word ‘supposedly’ “supposably”
Pronouncing the word ‘especially’ "Expecially’
Pronouncing the word ‘cache’ “cashay”
Pronouncing the word ‘larynx’ “larnix”
Pronouncing the word ‘across’ “acrost”
Pronouncing the word ‘jewelry’ “joolery”
…to name a few. 
Preach it! Every one also on my list!
Hey, nobody’s human.
I am totally guilty of this one. I almost always catch myself, though, as I know it’s wrong. I also have a tendency to say “controlative” which is…not a word. I have mostly beaten myself into the correct word use. 
Use of except in place of accept.
Viola when meaning to write voilà, or worse, writing ‘wallah!’ or some such.
In Diggstown, Bruce Dern used the phrase “tear this man from limb to limb.” It REALLY gets on my nerves, as the correct phrase is to tear limb from limb.
My SIL drives me nuts using the word “unthaw” to refer to the process of “unfreezing” something. I don’t actually smack her with a wet trout, but I’d like to, all the while shouting, “It’s THAW!! The word is THAW!!!”
Unravel is a lot like unthaw, eh?
One of the funniest lines in O Brother Where Art Thou? is after one of the guys spills a big batch of paper money onto the ground and one of the travelers says something like “Friend, some of your folding money has done come unstowed.”
Um… why?
Lemme axe you a question.
AAAARRRGGGHHHH!!!
My wife is notorious for these.
“Half a dozen of one, half a dozen of the other.” No, the idea is that you use two different ways of saying the same thing.
“That model is so thin. She’s very stealth.” Uh, I think you mean svelte.
My friend’s daughter does it too. “He’s not very smart. His head must be shallow.” I think you mean hollow.
I once chided one of my employees for responding to a customer with an unintelligible email. So she wrote another one to the customer to apologize for the"confusement" she caused.
One of the possible meanings of unravel is an autoantonym, but generally, unravel means untangle - which is the way it’s commonly used.
And unstowed means loose, which makes sense in the quoted context.
But unthaw means to freeze.
That’s querstion.
Yeah. My position on that is this- Toeing the line sounds ridiculous. Completely.
Towing the line makes me picture a guy pulling a barge with a tow line… He’s towing the line. He’s doing the work, if he doesn’t the barge might be lost to the river. You do it right or something bad might happen.
Toeing? Seriously TOEing the line. Utter bullshit.
That’s just my position.
