Taking the P

[DaveDiamond]

That may be, but according to "Wobbly Bob" and his friends, it meant Prisoner Of her Majesty) And yeah I know, that is what the brits called the Aussies since it was once a penal colony, but they had switched it around, and they weren't the only ones I encountered who meant it this way.

These guys were pretty old, as evidenced by them thanking me several times for the fact that the "Yanks kept the Japs from invading Darwin when the POMs abandoned them". And yeah, I know, the brits had problems of their own at the time. These guys were also openly hostile to any of the "abbos" who entered either of the two pubs, which led to some uncomfortable moments. It was off season, tourist wise, the time of year of stinger jelly fish, salt water crocs breeding and stifling heat, but at least there were mostly only the locals around.

Yeah, at School it was said that POM, or more correctly POME was on the back of their shirts, Prisoner of Mother England. Like WOG being on the other immigrant's backs, Working for Our Government.
Reading literature written by the "common man", anecdotes, journals, and specifically war journals, Pomegranates does come up a lot.
I'm not qualified to give a definite answer.
I've also got about one swallow left of my third 1 litre bottle of 6.5% homebrew Cider, I'm barely qualified to go for a p*ss!
