Any cute LOTR/Hobbit nicknames for guys?

My boyfriend (M27) is a HUGH LOTR/HOBBIT fan, he geeks out to it like Harry Potter or Star Wars fans do.
He's taken to calling me (F24) his "Precious" (The One Ring) or "Elven Warrior Princess" (Tauriel: non-canon character, yes we know she isn't REALLY a princess, or in any of the books, but that's besides the point). The latter in reference to Kili & Tauriel's love for one another, since my boyfriend is visibly shorter than myself.
I had told him I was going to call him "Kili" & "my sexy dwarf" from now on if he continued to reference LOTR.

I need help here... I was wondering if there are any good nicknames I could give him?
