Usually a cute girl whose cuteness is overlooked due to her tendency to be extremely whiny and/or needy. When she isn't acting like her usual big fucking baby self, she comes across as very sophisticated - because she is. She is also of abnormally high intelligence...
she just tends to be so damn annoying sometimes!
Sometimes shortened to BFB
Big Fucking Baby: I don't know if I want to go to this party tonight because Im so tired and I just dont feel good... it's cold outside anyways and I think it's going to storm later and so I think I should just stay in tonight. I'm really hungry... Feed me!
Friend of the BFB: Oh my god, shut up, you're such a big fucking baby
