I know some people do and that particular term goes back to the 30s and 40s and nothing new. I personally never liked being called "Baby" and would let the guy know straight up front I didn't. I don't mind Babe or Hon from my husband. i think that it's a cute term to show the affectoin that someone has for you. but personally i think it's a tradition and evryone seems to do it. but i really don't think it means much.
