feyfriend
a genderless relationship term that can be used if your partner is agender, nonbinary, or other non-conforming gender identities. replaces the words "girl" or "boy" but keeps the suffix of "friend" so that this term fits nicely with the others. (also kind of sounds like your partner is from a fantasy realm, with "fey" sounding like "fae", another word for fairies/faeries).
"Raine is agender, meaning that they're neither a boy or a girl, they're my feyfriend."
"Amy's not answering my calls, her and her feyfriend are probably gettin it on in the woods!"
