How how how???

So I've always been curious on how you Alpha people come up with the rank names of your packs!
I know some stick to the basic Alpha, Beta, heir, hunter etc name, but when you come up with all the different ranks ie Abavens rank names, Dono's rank names, Imperiums names, etc.

A lot of those names are quite interesting and i've never seen before. Like, ever.
So do you come up with them on your own? Or are they based off other ideas? How do you come up with your rank theme? Explain to me/us this sorcery! x3
