Obama Baby (n)
A child conceived through celebration sex after Obama was proclaimed President. Those election night parties led to lots of sex, and presumably lots of babies, too.
I did some math:
If fertilization occurred on November 4, 2008, these babies should be born on or around July 28, 2009. (Since gestation lasts about 38 weeks.)
So, if someone you know announces they are having a baby at the end of January (approximately three months from now), then they could be having an Obama baby.
