Babydoo- a way of saying "Cutiepie." Also a way of getting a girls attention and hopefully getting her number by using your wide vocabulary. babydoo is best used in a deeper voice to make it sound alot more sexier than it actually is.
an example of using "Babydoo" would be, is if you walk into a strip club and see a wonderful looking woman dancing on top of the stage. you could say "Hey Babydoo over there, how 'bout you come over here and give me that number." hopefully she will and otherwise she will laugh in your face and you will have to use it on another woman who will like your sense of humour.
