Ahh maybe that’s it. Old slang that’s not used often enough these days.
Good luck reading an article about Meta Raybans without running into the term. That said, the whole smartglasses thing seems to be pretty dead as a concept - at least in part because public opinion is not on the side of folks wandering around with stealthy cameras on their faces
I have actually looked into meta glasses a number of times. Never saw the term. Learn something new everyday thanks for sharing this old term with the group!
