It depends on where you come from. In the US, at least around here in Chicago, all the earrings come in "gauged" sizes. So, 6g, 4g, etc. I use the word gauge when talking about the size of the earring/hole, because that's what they come in. I've friends in other places that use measurements, 3/4, etc. But if I'm just referring the that fact that the piercing has been enlarged, I use stretched.
Although I don't think it really matters, everyone usually knows what you're talking about![]()
