it's common use rhyming slang, not meant to be offensive at all.
I never heard this expression until I started using AB. I vaguely remember posting specifically to ask you what it meant. I have seen you personaly or others, on your behalf, explain its meaning to other AB members who are, at the minimum, "middle aged", on at least five other occasions.
Enough recurrences for me to believe that most non-Londoners have never heard the expression used.
It does not feature on telly or radio. Not PC, I imagine.
I somehow spent 15 years in London without meeting anyone who professed to be cockney, or ever used that phrase.
I am English but still dislike the sight of you poking them with a stick. You're making us look bad.
