(notice - I have no idea how this would work with our non-binary pals)
I've seen so many different ones which mean the same
Ex. Slytherclaw and Ravenin, Huffledor and Gryffinpuff
What I think is that it works just like (straight) ship names
Ex. Ron x Hermione, Romione. Male x Female
So, let's take me for an example: I'm a Ravenclaw and a Female. My hybrid house addend is Slytherin. So...
Slytherin x Ravenclaw would be the order, so I'm a Slytherclaw.
If I were someone else (male) and were a Hufflepuff and Ravenclaw hybrid,
Hufflepuff x Ravenclaw = Huffleclaw
The opposite would be Ravenpuff
Let me know what you think!
