Do you class knackered as swearing?

I have always thought of it as a mild swear word. A word I wouldn’t want my younger children using but wouldn’t be too bothered by a teen (but not to their grandparents) type word.

There is a current radio ad using the word which made me think about it earlier. I was surprised when I heard it and didn’t think it was a word I’d heard used in ad’s before.

It used to mean a specific type of being tired. As in, after sex tired.

Yeah I used to get told off for saying it.

Yes tired, but IMO not a particularly pleasant way of saying it. I do say it, but wouldn’t want my 5 year old saying it.

That doesn't make it a swear word though

Where I am from (North East) it isn't a swear word and often used to describe someone as looking tired (ie you are concerned about how tired someone is) but I live further South now and it is definitely seen as an insult if not a swear word per se.

Learned this the hard way 🫣

I’ve lived down south my entire life and it’s never been a swear word where I am

I couldnt care less if my kids said turd.

Edited

It’s funny isn’t it. We attach different meanings to words based on our lived experience. I’m in my 30s in the south and it was definitely considered rude growing up. But other words mentioned on this thread are just used in everyday language.

lazyarse123 · 14/01/2026 20:29

When i was growing up it was considered rude rather than swearing. I don't like hearing children say it.
I was surprised to hear Starmer saying it today and saying the country was screwed by the torys. Came across as uncouth and like a child that had just discovered the word fuck.

I think knackered isn't a swear word but it's vulgar and certainly shouldn't be used by children. I wouldn't use it in polite company. I'm in my sixties and understand it originally to mean exhausted as in after sex, so quite a rude word.

Bugger is definitely a swear word. Certainly not to be used by or in front of children. It's a horrible word, it means putting a penis in someone else's anus, so is pretty disgusting.

Sod is an abbreviation for sodomy, the same meaning as bugger, so again pretty rude. Children shouldn't be using it.

Crap/shit/turd are rude and children shouldn't hear or use.

I always think that any words you wouldn't use in a formal letter or essay type of thing or use in front of a class of children should be considered as rude.

You’d hate my house 😆

Didimum · 14/01/2026 20:28

When I was younger it was commonly accepted to mean tired from having sex. I don’t think it’s a swear word, but I wouldn’t want my kids using it for this reason - though I don’t think that meaning is widespread!

VillaOfReducedCircumstances · 14/01/2026 20:28

I actually feel in my heart 😄 that it’s a moderate swear word, but I know that not everyone does.

I always feel a bit shocked when I hear it. I wouldn’t want my teen to use it.

MNLurker1345 · 14/01/2026 20:28

@DuckbilledSplatterPuff “I'm cream crackered….”, my SIL actually says this to me when he pops in for a cup of tea after a hard days work.

He considers me a bit prim, but I do like a bit of the cockney rhyming!

Liftedmeup · 14/01/2026 20:28

Yes, knackered has nothing to do with sex and never did. It relates to knacker’s yard.

ChequerToRed · 14/01/2026 20:26

Knackered, as has been said, is from knacker’s yard where old and worn out horses were sent before going off for pet food and the glue factory. It has nothing to do with sex, I have no clue where that weird idea must have come from.
This all reminds me of my rather religious BIL and his wife, very down on swearing but will happily use ‘blimey’, ‘crikey’ and other oldskool exclamations without seemingly realising their blasphemous origins but won’t tolerate the robust, but once upon a time perfectly acceptable in polite company, Anglo Saxon and Middle English that’s evolved into many of our current swear words, and no, I haven’t told them because it amuses me.
I do wish people would look into the etymological roots of words before they get their knickers in a knot about them, though.

TheSmallAssassin · 14/01/2026 20:25

I love the way people are posting up definitions off the Internet as if that is somehow more authoritative than actual people who've spoken the language all their lives.

I'm just wondering if anybody else has got a decent way through life (I'm 46), without ever having heard it said that 'knackered' specifically relates to being tired after sex? Hand on heart - this thread is the first time I've ever heard that!

Never heard that. I've always known it to be rude in a mild way and to come from the knacker ie the person/ industry which kills and repurposes old useless animals.
Learned it from Animal Farm when Boxer (RIP Boxer) is taken away in the knackers van and sold for glue to buy whiskey for the pigs. #spoiler 😂

DappledThings · 14/01/2026 19:43

First time I've ever heard anyone connects it with sex.

news to me too.

Always thought it described just being so tired out that you were only fit for the knackers yard. One of our teachers used to say "Would you say that to The Queen?" Probably not as she was very fond of horses.

"I'm cream crackered Ma'am." would probably be acceptable I guess.

It used to mean a specific type of being tired. As in, after sex tired.

Sounds like you've been reading the Urban Dictionary!

It's slang but definitely not a swear word and I've heard all sorts of people use it in various situations all my life but never in a sexual context.

Zanatdy · 14/01/2026 20:22

When younger I always thought same as OP as in its a mild swear word, but I don’t bat an eyelid when I hear it now.

MNLurker1345 · 14/01/2026 20:22

Apologies is this has already been posted. From Chat GPT -

“I’m knackered” comes from knackers’ yards.

The short version

A knacker was a person whose job was to collect animals (usually horses) that were old, injured, or dead and process them for glue, leather, or fat. These animals were sent to a knacker’s yard.”

Dissappearedupmyownarse · 14/01/2026 20:18

The context in which it is used has changed over the years to it now having lost its original meaning of tired after sex because a man's 'knackers' being used; a bit like I feel completely bollockeds (sp)
I feel most swear words have lost their energy or intended imact over the year's because of over use. Take 'bugger' for example. Its actually a very vulgar term of phrase and I feel that because most dont understand its true meaning (anal rape to save anyone a google search), they think its mild compared to fuck off....

That wasn’t its original meaning, though.

Also, nobody says ‘I’m bollocked’ to mean they are tired after sex.

Lovelynames123 · 14/01/2026 20:21

Definitely not a swear word, my dm swears maybe 2 or 3 times a year but will regularly say knackered!

I’ve never heard the connection before today, early 40s

I don’t think it’s a word I’ve ever used but I don’t swear and I wouldn’t think it was a swear word 🤷‍♀️

Just found this online to answer your question:

Formerly considered a rude word – possibly implying that the subject was exhausted from having sex, perhaps due to conflation with knackers (“testicles”) – and still considered offensive by some (primarily older British people).

I will always laugh now when someone tells me they are knackered! And that’s me educated - I’ll not be using it again either.

weathervane1 · 14/01/2026 20:20

Isn't it related to the business of a knackers yard? That's what we used to call the abattoir when I was young in the 70s and 80s. It's where tired and run-down animals went. It's the first time I've heard of a non-swear everyday word possibly being considered to be rude. It's usually the other way around where swear words lose their potency to offend over time.

Simplelobsterhat · 14/01/2026 20:19

TheFireHorse · 14/01/2026 20:16

Maybe it's to do with age, I'm 60 and it was definitely a word you were not allowed to say when I was young.

I still get a little shock when I hear young kids saying it :)

It makes me laugh when young kids say it but that's because to me it sounds like something an older person would say, not quite right coming out of their mouths. I hadn't considered that might be because it's swearing though.

FrodoBiggins · 14/01/2026 20:19

shellyleppard · 14/01/2026 19:39

I always thought it meant really tired/ broken. Not a swear word. But what about bugger?? Do others class this as a swear word

It's something to do with killing an animal when it's past its useful live. My mum would class it as a swear word and would have told me off for saying it as a child. Akin to "bloody".

Yes bugger as well is a minor swear word. Means fucking someone up the arse though so I can see more clearly why it's offensive
