TikTok and Mastodon have taught me that "breedable" (or sometimes "submissive and breedable") has become a bit of a synonym for sexually attractive, "often used with irony or playfulness" as the Urban Dictionary puts it. Which is great good fun and I love it.
However, I feel like I'm seeing it most often, perhaps even almost exclusively, used to describe and compliment transwomen. Is that a genuine nuance of usage, or is it just because of the demographics of Mastodon? #Breedable
