A pet name or term of deepest endearment for a significant other who is both your best buddy and your romantic interest. The term was derived by combining "buddy" and "baby" = "bubby". The one you love, the one you adore - as opposed to the patronizing baby. A bubby is special because it is not a babe, baby or boo it is one specific person that is completely unique and precious in your life. Other abbreviations include bubs, bubbsie, bubster, bubba, bubsky etc.
