I've heard it called 'Deli belly' for years.
Also with that other news link above, I'd heard the term pikey for years also, it means someone who is cheap . . . then they roll out some idea that it's apparently also a reference to travelers.
Oddly just this morning, I was checking something on the net about the phrase 'nitty gritty'. I had heard that it was thought to be a reference to slavery.
To explain we have a new guy just started at my work who is from West Africa. One of the staff used the phrase 'nitty gritty' in conversation with him. I cringed - slavery reference, good idea.
But from what I was reading on the net, there's been people saying that it's a slavery reference, but it isn't.
