Amphiterae

Amphiterae (or Amphiteregender) is a xenogender that is small, mischievous and sneaky. It collects or hoards other terms that fit, and often fluctuates between terms that are considered their favourite. This term’s definition was created with dragonkin in mind, but it can be used by anyone.

History and Flag
Amphiterae was coined anonymously. The flag was designed by since deactivated Tumblr user nebularomantic.
