"Jalopy" is still being used, in some sub cultures. Mostly nowadays as a reference as a 2nd or 3rd gen rundown car. It was a POS rattletrap to begin with when THAT guy got it, and it got worse.
OK whippersnappers. This is SoCal. "Jalopy" came from the Mexican town of "Jalope", a town once infamous for it's auto repair, resell, customize- and sometimes parts of vehicles with unknown ownership would be reassembled into a different vehicle. Folk here would go there for a weekend, and get their cars reupholstered, carpeted, headlinered, repainted, and whatnot. And, if you were that special blanco gringo who came down like an uppity drunk tourist in Disneyland, your upholstery could be stuffed with used stable hay, and your tires replaced with those more of a vintage quality.

Segue: if you're into hot peppers, there is/was a breed called the "Bhut Jolokia" I've grown them, and while not the hottest variety out there they do live up to the name. Too many, too often, too soon and the next day your backside will resemble the condition of said vehicle. You'll have a "Jalopy Butt".

And yes, I has grandkids and great grandkids, allways reminding me that this is a new age. Most kids don't have phys ed anymore, exercise, play outside, do sports, etc. They're "inside" people. Most of the people they know are thin skinned, #metoo, iPhoned, and can't get into a restroom without a few more selfie shots in the mirror. Relationships and friendships are built on favors and alliances.
Times Have Changed.
I wonder what their kids and grandkids will be like.

Actually, it was Snaggletooth the Lion.

I think if the average person were to hear the expression "hell's bells" today, this is what would come to mind.

Some of the old expressions were just fun while others had a message as "serious as a heart attack", while others were "as funny as a screen door on a submarine".

I love my wife but oh you kid.
Twenty-three skidoo.
Heavens to mergatroid - Snagglepuss, on the Yogi Bear show.
packing a heater, a roscoe, “I jammed the roscoe in his button and said, ‘Close your yap, bo, or I squirt metal.’”

“The flim-flammer jumped in the flivver and faded.”

“You dumb mug, get your mitts off the marbles before I stuff that mud-pipe down your mush—and tell your moll to hand over the mazuma.”

“The sucker with the schnozzle poured a slug but before he could scram out two shamuses showed him the shiv and said they could send him over.”

Why get in a car when you can hop in a boiler?
Why tell someone to shut up when you can tell them to close their head?

Why threaten to discharge a firearm when you can say, “Dust, pal, or I pump lead!”

With thanks to "Twists, Slugs and Roscoes", a glossary of hardboiled slang. I had to look it up when I was reading all those Philip Marlowe stories.

And my wife's favorite, "My heavenly days." I call her Aunt Bea whenever she says it. In a loving manner of course.

Such wonderful memories. Wish we still had our old jalopy.

I use all these words and expressions. In fact, I was talking to a bank representative on the phone last week. She told me about some investments I should look at when "Heavens to Megatroyd" fell out of my mouth. She cracked up. "I haven't heard that in ages," she said.

When my father said “I’m going to get my belt”, it had a totally different meaning than it does now 😃

I think Heavens to Mergatroyd was also used by Ragland T Tiger, the sidekick of Crusader Rabbit. They lived in Gallahad Glen on early Saturday mornings in the 1950's. I just loved them.

My dad did not say it......he simply snapped it out of his belt loops. What a terrifying sound that was!
It still makes me cringe. I do it now an again just to see if I am over the feeling. Nope...not yet.

My daddy had an alligator belt he would whip out of his belt loops. My mother had a wooden spoon. If I messed up I'd get the wooden spoon and then sent to my room to wait for my daddy to get home from work. When he got home, Mother would "fill him in". The worst sound ever was the sound of my daddy coming up the stairs. Second worst sound was that alligator belt being pulled out of his belt loops. Gotta say, I did become a better kid quickly.
