Your Cat’s Deid.

“Your cat’s deid”.

Remember that?
Remember people used to say that to boys in school who had trousers like this:

Why was that?
Short trousers.
White socks.
Slip-On shoes with tassles if you were very unlucky.

What’s that got to do with cats?
“Your cat’s are deid mate”.
Where did that saying come from and what’s it got to do with this:

Was Michael Jackson involved?

I remember these poor guys at school who constantly had to put up with:
“Here mate, your cats are deid”.

And then later on,
That saying changed into people making a simple gun noise followed by a Miaow.

What the fuck was that all about?
Was it just a Scottish thing?
Anyone know anything?
