Here you go @yyy . Sorry I only found it in German - English googling brought only porn sites. This is from a (the?) German swinger community website and contains a pretty exhaustive county list. Google translate works reasonably well. And no, the translation seems not wrong for “Roman”. No idea why “Indian” seems empty in the English autotranslate, though.
Anyway, it’s funny to see a horde of pervert Germans discussing passionately about this being" too pervert"
Oh, and your “shower” seems somewhat related, as I was surprised to learn.
I don’t think it’s been regularly used in the US since at least the 80s…I knew what it meant but no one ever used the term. It was extremely common to hear in China in the late 90s and early 00s, though.
I’ve never heard this before. In America to “French” means to kiss with the tongue.
Good point. I do use and very much prefer DeepL for translations. On the other hand, I expect anyone following that link would likely be using google translate in their browser.
May have died out since the 60s. It used to be regularly used when I was in high school (admittedly a looong time ago).
OTOH, googling it brings up pages of definitions and usages, and none of them seem to regard it as fallen into disuse.
