Outherine, for those who don't know, is a gender alignment for those who aren't feminine, masculine, neutral, or in-between, but also aren't xenine, while still having a strong sense of gender.
Ousei (γͺγ¦γ»γ€) comes from the Japanese word yousei (ε¦η²Ύ), generally meaning fairy. This was chosen as the symbol for Oberon, the king of the fairies, is often used as an outherine symbol. The Y is dropped to make it sound a little more like outherine.
This was coined by @mothy-creations and I! I came up with the name, and thxy created the symbol & ouseicon flag!
