There are other theories that the OED dismisses.

A few years ago, the term was officially deemed "no longer offensive" in Australia -- as if officials can decide for individuals what is and isn't personally offensive.

I don't know about South Africa but Australians generally only use the term to refer to the English. Not the Scottish or Irish.

Only definition I ever heard over there is this one:
POMMY = POME = Prisoner Of Mother England
