The severity of each level is different
I think matching wine glasses is relatively uncontroversial, but also understandable if kinda mismatched. A contingent of matching tumblers is also fine but you need the random pint glasses too at the very least. I maintain a fully matching set of mugs is a red flag








I’d say something like Seinfeld or Friends is probably it, there’s still channels showing reruns of these all day long across the world.
You’ve got to consider stuff that was popular and universal enough to get translated to many different languages and then still get rerun in those countries too
