Furry lingo/slang

[Quail]

I have a few to add:

Fursona: an animalistic alternate persona or avatar
Avian: one who has a bird or bird-like fursona
Scalie: one who has a fursona that is usually covered in scales, such as a snake, lizard, dragon, etc

[Katt]

Not to forget, although it's not quite a furry term, or is it?
Tied - going past a knot on a toy and getting it intentionally stuck.
Did i get that right?

I've never heard that particular term, I've always heard knotting.
That may be the unintentional one though.
