One turn of phrase I’ve always laughed at is Eurotrash. I find it amusing to see inter-EU rivalry but it is grossly unfair. To date, the French in shops and bars I frequent have been treating this big galoot with the respect my schoolboy French does not deserve!
I came across the pejorative term in the 1970s in London where there was a lot of rivalry with their cousins across the channel.
Apparently the Yanks like to use it too but part of my sojourn to Europe was to get a feel for the eurozone as it remains a worrying fly in the ointment that I’m most concerned about.
