You have a passion for fun questions to ask your boyfriend
But make sure not to call her anything that is connected to heavy meal, like pork chop. She will definitely not see that as cute and will probably think that you see her as fat.

She will more likely be offended if you call her a gerbil or anything from the rat family even though you may find the animal cute.
