Old fashioned expressions you still use.

I'll knock you into kindom come. (Or next week)

Well, I'm clearly daft. That should have read "I'm not as green as I'm cabbage looking" ?

My Mum:

'Champagne taste - beer money' about someone with airs and graces

'Couldn't stop a pig in a passage' someone bow legged

'I'm not as daft as I'm cabbage looking' - to someone who tried to fool her

'A face that only his mother could love' - about someone in love with their own appearance

'All mouth and trousers' - a man too full of his own importance!

My mum said that too Kate. I always think its a Black Country expression.
A very distant relative - their cat walked up our entry.

Some of these bring back memories. My husband still says this. If someone is bow legged, he says 'He couldn't stop a pig in an entry'.

My mum used to say she'd swing for us.

I remember nearly all of the above, another my mother said, ‘you’re not worth swinging for’. Must have push her nearly to the edge.

I used to say,”Woops a daisy!” if I did something wrong at work to the amusement of younger colleagues.

HKLP!

If it was raining, my mother always said "don't forget your gamp. Never umbrella.

Daylight robbery ! My mother always used that expression when something was too expensive .

The only ones I have never used are pip pip and the one about witches.
I shall try them out on my children. My guess is they will never have used a lot of them but will understand a good many.
Yammy. In Scotland it is “haud yer wheesht” meaning stop speaking or be quiet.

What's for dinner ? Bread and slap or bread'n'erring.
I couldn't eat a stuffed raisin---mum after a big dinner.

Next door neighbour telling mum he'd just put manure on his rhubarb----we have custard on ours Mr S.

Another mean relative----I bet he can peel an orange in his pocket.
You're the biggest mug on the pot stall---if dad had been diddled after a purchase.
She's got a face like bad fat-----a miserable neighbour.
If I was sulking mum would tell me I'd stick like it.

I couldn't spit sixpence---mum when she was thirsty.

BridgetPark yes I've heard the " beans " one except dad used to ask how many blue beans make 5----believe it or not I paused when he first asked that

Wasn’t it mercury they used in hat making?

One my Mum used ( usually about me) ‘you could jaw the hind leg off a donkey’ meaning I never stopped talking.

When things did not go right ‘well it was the best butter’!

My dearest departed father had this one, I Know how many beans make five... in case anyone thought him not quick enough to catch on. I believe it may have been from the military. Anyone else heard it? The reply is..two beans, a bean, a bean and a half, and half a bean...

My mother, a Brummie wench, used to say of someone being over helpful, ` Proffered services sometimes stink'. Never heard anyone else say it or seen it in print.

Charlie's dead was said here, for a slip showing.
It sounds ridiculous, now.

How about "It's snowing down under" if someone's petticoat/slip is showing beneath the hem of their skirt? Probably no-one wears them these days.

DH said that one of the saying reportedly going out of use is "Mad as a hatter" because hats are no longer made using lead, which poisoned the hat-makers.
