Sabriel is nice, though I don't like the ship itself. I loved the book as a kid so I approve of this ship name. Sassy is another good one.

Snack is a truly classic portmanteau. If I ever got back into the Harry Potter fandom, I'd hope that ship would still be around for me to get back into.

I also like how the Katekyo Hitman Reborn! fandom uses numbers to refer to characters based on their names so instead of saying something like, 'I ship Tsuna/Hibari', you'd be all, 'I ship 1827', which is pretty cool.
