It's a bit hard to tell really.[...]
It's also in Angela's Ashes (which isn't American), I believe.
I should have clarified, you're right. This is dangerously off-topic of me though...It's a bit hard to tell really.
It was written by Frank McCourt who was born in Brooklyn, lived in Limerick (Ireland) between the ages of about four and nineteen, then went back to the US.
The book is mostly, as I recall, about his time in Limerick.
And yes, the term knee-trembler is familiar in Ireland too.
I have never known a man use a blue rinse, but I suppose they might.<Is there a single blue-rinse Tory who doesn’t fancy a knee-trembler with Boris Johnson?>
So this 'metaphor' should be valid for male and female blue-rinse Tories alike? Or is 'blue-rinse Tory' female only?
