A baby born to parents 9 months after the end of the world in 2012. The parents were most likely drinking and made an excuse to why birth control methods were not needed. The excuse was the 'End of the World Excuse.' Like the baby boomers but larger and more babies. (Also See: 2012 Party)

ii. OMG everybody knows your a 2012 Baby if your birthday is in September of 2012.
