In Cockney rhyming slang, the word "Greek" is replaced by the word Bubble.
It comes from a dish that very few people now eat, but which was popular amongst Brit working classes in the past. "Bubble and Squeak".
From the BBC cooking website - "Bubble & squeak should be on everyone's radar come Christmas time - it's a great way of using up leftover mash, sprouts and cabbage"
Athens has more Greeks in one city than anywhere else. However, there are more Greeks in both London and Melbourne than any other Greek city.
So is it Bubble script?
