These anomalies of formalized language tend to be most pronounced during youth or during a maturing phase of life. Sadly, the language of a Senior, or Senior Citizen, may be misinterpreted by earlier generations.
One way to solve this, would be to compile a "Senior Citizen Dictionary" that would explain the world as it might be viewed by your man or won 65 and older. I say this as one who would know.
The Senior Citizen Dictionary, which I believe could be as successful as the "mansplainer," would contain dictionary entries solely based on relative senior experiences.
For example, under "Golden" (Noun):
1. The stream running down your leg because you did not make it to the bathroom 2. the color of your urine because of dyes in your medicine.
3. The false idea that your latter years in life will be filled with smiles, happiness, and massive discounts on everything from steaks to new gutters. SEE Golden Buckeye Card fraud.
These definitions would require "as used in a sentence" sentences, like when we were in school.
TEACHER: Can you give an example of that in a sentence?
9 YEAR OLD: Yes, I can.
TEACHER: Give me a sentence with the word used correctly.
9 YEAR OLD: He correctly her mouth.
TEACHER: That is not a sentence.
9 YEAR OLD: It is too.
TEACHER: You are incorrect.
9 YEAR OLD: I know you are, but what am I?
Included in said dictionary would be words like "Epizoodie," which some old codger used to ramble on about to you...and now that you have gray or white hair, you have been dwelling on that word, wondering what in the blazes it means. So, of course, it goes into the Senior Citizen Dictionary.
It would be colored by your great grandmother who used the word incorrectly, spelled it incorrectly, but it was "a thing" to her...and very awful...so it goes in the dictionary...
Epizoodie (Noun, adjective)- Your grandmother's term for a horrible thing, likely a deadly disease. "I swear she got the epizoodie last week and it plumb near killed her."
This grandmother did not know there is a term "epizoodic." Hence, it appears in the Senior Citizens Dictionary as used by the senior citizen.
Slang words from the 1940s might appear because your mother used them. Since she called the stupid guy who dropped a pass from the quarterback a "dumbbunny," that entry would go into the Senior Citizen Dictionary. Forget about it being a word that shouldn't belong in the standard dictionary. The Senior Citizen Dictionary should supersede such a "narrow view."
As you can plainly see, this proposal would very likely be a best-selling reference text, right up there with The Oxford Dictionary of Verse and The Toilet Seat Reference Tool.
Perhaps, I will go to Wix, Squarespace, or another website builder and craft a slick-looking site to market and sell the new dictionary, offering a free T-shirt with every sale. I am sure we could make big money...mucho dinero...but right now, it is 10:59 PM and I've one minute before my bedtime and all those pills and I have to strain my urine for the doctor and i have to gargle with salt water and i have to check my oxygen level, so i've no time for it. Besides, I have to eat a handful of nuts before bed, 'cause Momma always said if you don't eat nuts before you go to bed, you won't be able to poop in the morning.
