look up any word, like cunt:
 
1.
Noun. Individuals who were born or grew up during the bubble economies of the 1990s and 2000s. When used as a pejorative, "Bubble Baby" refers to anyone steeped in the ethos of the bubble era. Bubble Babies, in this sense, are the worst examples of this generation. They are used to having everything handed to them and act as if they are entitled to a life of comfort and prosperity. They tend to view any inconvenience to themselves as arduous and unfair, and never accept blame or criticism no matter how well-deserved.
