Swearing has likely been a social phenomenon since an early caveman caught his thumb between a rock and a hard place.

Yes, it was long considered uncouth and a certain sign of a weak vocabulary. But as society has coarsened in recent times, so has the language, even in public. The ubiquity of cell cameras and these d****** recording devices has captured the foul moments for all to hear.

You may recall back in 2010 at an historic bill-signing the Vice President  of the United States, Joseph R. Biden, on national TV muttering into the president’s ear and a live mic the immortal words, “This is a big f****** deal.”

Before that, President Obama’s friend and fellow Chicago pol, Rod Blagojevich, was caught on tape selling political favors for to any g***** sucker with the money to pay him. The Illinois governor was impeached, convicted and sent to f****** federal prison for a dozen years.

As Obama’s White House chief of staff, now Chicago Mayor Rahm Emanuel was famous for his frequent use of the f****** f-word.

Of course, public swearing is a bipartisan blasphemy. An open mic caught Vice President Dick Cheney calling one passing journalist an a******. And swear words have now become expletive exclamation marks, as in no f****** s***!

If memory serves, candidate Donald Trump uttered more than a few curse words during the late, unlamented 2016 presidential campaign, the least of which was an eight-letter, barnyard epithet. Some examples:

“They’re ripping the s*** out of the city.”

“We can’t get a f****** school built in Brooklyn.”

“I’m gonna bomb the s*** out of them.”

“You’re not gonna raise that f****** price, you understand me?”

“Listen, you mother-f******, we’re gonna tax you 25%.”

“What’s the difference between a wet raccoon and Donald Trump’s hair? A wet raccoon doesn’t have seven billion f****** dollars in the bank.”

And look what happened! Dumba** Americans elected the son-of-a-b**** f****** president.

Imitation is indeed the highest form of flattery. So hey, if it worked for that d***, maybe swearing could help some f****** Democrats defeat that son-of-a-b**** in four years. As our astute journalism colleague Alex Roarty notes over at McClatchyDC.com, desperate Democrats are now joining in the f****** parade of foul mouths.

After firing every f****** person at the g****** Democratic National Committee, its new dips*** chairman Tom Perez declared with no f****** sense of irony, “Republicans don’t give a s*** about people.”

And then comes another New Yorker, Sen. Kirsten Gillibrand, who replaced H****** Clinton. Gillibrand is a Roman Catholic, prayer group attendee and the mom of two. “If we’re not helping people,” Gillibrand notes, “we should go the f*** home.”
