Couples, what secret language do you use to tell each other details that the company you're in doesn't understand or notice? - lemm.ee

What words, phrases or signs do you use and how do you get your partner’s attention?

My spouse and I lived in a bunch of countries over the years. We speak Quebec French, English, and Spanish, as well as a smattering of Chinese, Bulgarian, Korean, and a few odds and ends here and there.

We basically speak whatever we think people around us won’t understand. Very colloquial Quebec French in non-French-speaking countries, Chinese around white people, Bulgarian around non-white people, or even a cryptic mix of everything when we’re not completely sure.

We figure anyone who understands is probably someone we want to know… Hasn’t happened very often, but it does happen. So far we weren’t saying anything overly embarrassing when we got caught, but we sure as hell have no filter between us because of this!

I've taught my husband to speak a bit of Japanese, but we don't use it this way because that's extremely rude.
That’s probably a cultural thing, isn’t it? In diverse areas, people don’t expect to understand what they hear others say, so there’s no “Speak ___; we’re in ___” culture.
I’d say it’s more of a context thing. If you’re hanging out in a group of people chatting together and you code switch to speak to someone so nobody else can understand, that’s rude. If you’re just speaking to someone in another language on your own, nobody cares (except xenophobic bigots).
Oh, that makes sense. I didn’t consider anyone would do that.
