Babyluv

A name like "baby", "hunny", "jackass", "jerkface", "dumbass", "sexyface" or whatever else you call your significant other, that only they know you want them to feel completely loved when being called this. Sometimes these words become more like the person's name than their given name, it just fits. Stephen King uses babyluv in his book Lisey's Story. The name sounds awkward at first, but then grows on you.
