For HN'ers outside the UK who might be put off by the Godwin above: People here really do have strong opinions about Brexit, one way or another. It has been a central part of the news for many years now, and it has increasingly real implications for this country's future. I (also) don't want to delve into the political arguments, but to give you an idea of what's at stake, a Brexit-induced restart of the Troubles in NI is now looking more likely than it has for decades.
The point I'm trying to make here is that it's just not a topic that you can have a casual opinion on. Against that backdrop, using the term as a whimsical joke feels so profoundly distasteful that a lot of people here would probably ignore the business entirely.
