POME is an abbreviation for Prisoner Of Mother England. This is where slang term 'pommie' originated from.
Although technically this refers to the Australian population it would seem the tables have been turned to an extent, because the 'poms' are the prisoners, condemned to a life of pouring rain and crappy weather all 'round... with Australia as one of their top holiday destinations!
(Naturally, they still believe England is the greatest, and Australia is full of convicts.)
Also: pommie, pommie land
