All in the Family gave us Carroll O'Connor as Archie Bunker with his own personal lexicon of terms derived or mangled from existing expressions. He could try to give a good "euthanasia" at a friend's funeral or lament the "women's lubrication movement" and ask Edith not to ask about things that only a "groinecologist" should discuss. We loved his scripted mistakes because we'd all done something similar and we weren't alone.
Other great malapropists (I made it up) were the eponymous (lookit up) character from Richard Sheridan's 1770's play The Rivals who pretentiously declared someone to be "as headstrong as an allegory on the banks of the Nile" and another as having achieved "the very pineapple of success". Our modern world has produced a number of unintentional malapropisms. These were from the Wiki entry on the term:
Marjorie Taylor Greene, a very rude person in disguise as a U.S. Republican senator has railed against the "gespatcho police" who "fragrantly violated" the rights of those peaceful demonstrators at a Jan 6th event at the US capitol building, but then she probably believes, as did an Australian PM, that her party is the "suppository of all wisdom". And another member of Ms Greene's party stated quite clearly in a 2022 run-up that "this erection is about the people". He was no doubt prescient as "the people" of his state will discover over the next four years.
On the lighter side of unintentional malapropers was Yogi Berra with his observations that "Texas has a lot of electrical votes" and that a switch hitter "hits from both sides of the plate. He's amphibious" without acknowledgement of either electoral college or ambidextrous opponents.
Screen writers have always delighted in providing malapropisms for their characters with Archie being only the most recent in a long line of misspeakers. Norm Crosby made his comedic career on the effect of such scripts and besides noting that he needed an "altercation" to his ill-fitting suit, he said reading education was important to prevent the problem of "illegitimacy".
Malapropisms either accidental or scripted aside, I have my own set of idioms in our language that will bear deliberate adjustment for changing circumstances. Take Darwinism, for example, and poor old Darwin has been taken for a lot of examples, some of them most unpleasant. Darwinism has become the catch-phrase for "let 'em go extinct" and "social Darwinism" has come to refer to both the extinction of cultural groups internationally and the impoverishment of the under-educated or lacking-of-opportunity class in even 1st-world nations. I use a variation to talk of my garden.
Seasonal Darwinism is my expression in autumn to refer to a policy regarding my overgrown flower beds of let-em-survive or die-and-become-mulch. The weather figures greatly in the outcome.
Pre-emptive Strike was an ominous Cold War plan to "hit them with our missles before they launch theirs at us". We use it with bugs. What did you expect? Wait for the mosquito bite and a jury trial?
Power of Adjourney simply gives anyone the right at a boring gathering to declare "Stop the meeting! The bar is open" and that's "bar" as in drinks.
Acquired Impunity is bestowed when you know so much stuff that you can't be fired. And what's more, you have copies of emails and photos from the last office party.
In Flagrante Depicto should be explained to every user of every digital device. Don't post pictures of yourself or your body parts on social media. They live forever. Some high school students as well as politicians are still learning this, and there have been some tragic cases of exploitation and suicide.
A Reasonable Pout occurs because after she left pictures of lingerie on your desk, emailed you sales flyers from perfume shops and repeatedly brought up the topic of resort vacations in the south, you then bought her a cordless electric drill for her birthday and now you wonder why she hasn't spoken to you for the past week.
And what have you got to offer? Every family has a collection of these mispronunciations and they are invariably trotted out to and for everyone's general "abusement" at weddings and birthday celebrations. And don't plead the benign modesty of your old age. That went out with your lampshade routine on New Years eve.
