Quatorze?
:dubious: Someone’s been having a lend of you, mate. Unless you’re talking England in 1800 or so. You certainly would have given Jane Austen a fainting fit.
Frick and Freak are my f-words of choice, but Frack is climbing the charts, since it refers to an unpleasant thing that I frequently wish to be rude about (quite apart from any geeky Trek references
As a Watergate-era kid the first “swear word” I really remember learning was “expletive deleted”. Still use it.
Nowadays I find that a quiet, distinctly articulated “How provoking” or “Oh, for heavens’ sake” in response to severe pain or frustration actually scares people more than a bellowed “FUUUUUUUUUCK” or “GODDAMMIT!!!”.
Muffinfudger. Son of a bachelor. Corksoaker.
I use The Good Place non-swears sometimes, now, too.
Also, how could I have forgotten that I’ll also use the immortal not-really-swear words of Roman Maroni in Johnny Dangerously:
“Bastidges! Farging iceholes!”
I accept no substitutes.
Muscovy duck
Littleman offers “darn”. I went to a super-religious (Protestant-type) preparatory school. Aged 11, and “thinking no harm”, I described something to the matron there, who supervised our welfare, as “a darn shame”. She was as horrified as if I had let loose a copious stream of the vilest effing-and-blinding; and rebuked me accordingly.
I’m not so sure – I get the impression that Jane was a tough cookie in her way. She had a couple of brothers who were naval officers; who would, for certain, have been well-acquainted with a wide range of colourful language, via their crews. I wouldn’t be totally surprised to find that Ms. A. had, from that source, a grand foul-language vocabulary – which she quite possibly used when the occasion was appropriate.
Do “bad words” in – relatively obscure – foreign languages count as “substitutes”? I’m rather fond of, and sometimes use, the Finnish word for “devils”; which English word would seem fairly mild – but apparently, in Finnish the word is a serious “swear”. The word is “perkele” (you can roll the “r” as extravagantly and lengthily as you like).
There’s a guy at work who always says “dad blast” instead of taking his lords name in vain, “effen” instead of the F word, and
“snap” instead of the word for excrement.
He does this a lot. It’s irritating and the rest of us wish he’d knock that god damn fucking shit off!:mad:
Bingdoogit!
Fiddlesticks, bugger, freak or freakin’, and occasionally flip are all cursing substitutes for me. One of my wife’s is See You Next Tuesday - say the first two words out loud and you can see where it goes.
When circumstances lead to the need to use an expletive, but surroundings and company proscribe the use of the profane, my go to phrase is “exploding rainbow unicorn poop and glitter farts” gets the point across, and usually a chuckle as well which helps with whatever the stress is.
Jeez Louise!
Razzenfratz!
Crap on a cracker!
I’ve got a 10-month old granddaughter, so it’s time I work on baby-friendly cusses, I guess.
“F” words: Phooey, fiddlesticks, fudgsicle.
“G” words: Good gravy, goodness sake
Most frequent - expletive
Really annoyed polysyllabic words: “I wish that hadn’t happened” - the tone of voice makes it very clear what emotion I am expressing…
I’ve actually find myself now borrowing a lot from “Johnny Dangerously” ------ cork-soakers, ice-holes, and bastiges. Done with the appropriate bad accent of course.
Smucking.
Just kidding, no one would actually say something that lame.
I did pick up use of the word “Jebus” from Homer Simpson.
Bucket and utterly.
Yeah, Maroni from Johnny Dangerously is always good for not-quite-dirty words.
I also use:
“Freakin’”
“Rassenfrassin’” (Yosemite Sam, more or less)
“Goldurn it” or “Dadgum it” (said with appropriate hillbilly accent)
I was showing my daughter some pictures of baby bunnies I found in my yard this weekend, and she said that she hoped my dogs wouldn’t get them. I reassured her that El-ahrairah was watching over them, and she responded, “Hraka.” 
The ones that I can think of that are real euphemisms that I use regularly (in semi-polite company) are:
Holy Moly
Jeez Louise
Goldarn
Dadgum
Dadburn
sumbit (more of an elision than a euphemism)
freakin’
God bless America
More jokingly:
Criminy
Cor Blimey
Bloody 'ell
My SO’s parents are British and still view the use of Bloody as somewhat offensive. Mom will mildly rebuke Dad for saying it in public. They are in their 70s and 80s and have been in Texas for going on fifty years, so their use of British English may be somewhat ossified. But it appears that, in some circles, bloody was considered an expletive into at least the late 20th century.
