Follow-up bonus for the “Donor” reread post
Jun. 17th, 2026 03:07 pmCollecting a bunch of new thoughts I’ve had while trying to write some Little Sister D fic.
(As mentioned in the original reread post. Yeah, at least one fic of this is happening. I’m even starting with the fluffy fixit version.)

So I’m looking more deeply into contextual meanings and nuances of Chinese endearments, as you do, and it looks like “哥哥 gēgē” and “妹妹 mèimei” are the more generic terms for “big brother” and “little sister”. (They can also be used more broadly, to address older men/younger women who aren’t literal relatives. They’re warm and friendly without being over-familiar, as long as you get the age dynamic right.)
Meanwhile, “大哥 dàgē” is more specifically “eldest brother.” It’s the version you would use for an older male boss (and, in pop culture, a mob boss). The same site doesn’t say “小妹 xiǎo mèi” is “youngest sister”, just that it’s a more-affectionate diminutive of “little sister,” which in practice gets used for the youngest a lot.

In related news, “宝贝 bǎobèi” (“precious treasure”) is an intimate term for a loved one, especially a spouse or child…but it’s also used for favorite pets. And there’s a modern-day trend on shopping sites to use it for products, as a playful way to convey what a great valuable deal this is.
I’ve gotta have D use that one for Leon.
