Usually pet names for two lovers. These two people are so in love. It's a very cute and funny nickname, but they arent even embarassed to call eachother like this in public places. Usually when people hear them saying babyboobear to eachother they envy them and wish they could have their own babyboobear. Babyboobear's must stick with eachother through it all, no matter how hard it is! Because they absolutely NEED eachother!
Guy: You ma babyboobear
Girl: Oh I love you too, Babyboobear!
