It’s raining in Paris!

It was ‘Charlie’s dead!’ for your petticoat showing in our house. No idea why.

Yes Charlie's dead if your underskirt was showing. I can't remember any others.

Yes Charlie’s dead here too!
A really strange expression, isn’t it?
I wonder what the origins are.

Mind you, how many women/girls wear petticoats now? Virtually none, especially as 90% are in the dreaded jeans 90% of the time anyway.

There is a star in the East, (no idea why) meant a gentleman's flies were undone.

We heard, “It’s snowing down under” for a low hanging slip.

I believe men are told they are flying at half mast if their flies are undone. I think.

Same here.

My grandmother would always announce she was, ‘Going to see Auntie’ when going to the loo.

It was raining in Paris when my slip was showing and periods were referred to as the curse. I can't remember any references to undone flies but I like Maw's one and am just waiting for an excuse to use it.

I did hear men say that they are going to show Percy the porcelain when going for a wee. The memories are flooding back now!

I have heard pointing Percy at the porcelain

Snowing in Paris for petticoat showing.
Wearing your medals - flu undone

Fly!

Going to see a man about a dog - dad said that when he was going to the loo.

‘Aunt Jane’ was visiting…for your period
‘Charlie’s dead’ for you petticoat showing
‘Dark over Aunt Maude’s’ rain coming
‘A bit of blue to make a sailor’s trousers’. Sun be out soon

Pointing Percy at the porcelain I’ve heard men say that.
Your medals are showing or flying low for undone trousers.
Going to see a man about a dog was my uncle’s way of saying he was going to the pub. As a child, I could never understand why those trips never resulted in a dog.

I nearly died the first time I heard the expression for periods in French.
Les Anglais débarquent.
It goes back to the battle of Waterloo when English soldiers dressed in red uniforms caused bloodshed.

“Charlie’s dead” was always for petticoat showing, and it was “you’re showing your medals” for an open fly.

“It’s a bit black o’er Bill’s mother’s” indicated that rain was in the offing.

My nana would always say when she was going to the loo that she was off to spend a penny.

It was "Charlie's dead" when your petticoat was showing. (I found this very disconcerting when I had a boyfriend named Charlie)

My ex husband used to say "Has Mrs Johnson arrived?" referring to my period.

Spurs at the bottom of the league, for do up you flies !

You're Flying without a Licence, meant your flies were undone.

It's snowing down south... Petticoat showing.
