Speaking at Virginia's George Mason University this afternoon, President Obama told the crowd he knows why his rival Mitt Romney has been "backtracking and sidestepping" so much lately: He's suffering from a condition known as "Romnesia."

Obama went on to list a few of the symptoms so people at home could avoid catching it:

If you say you're for equal pay for equal work, but you keep refusing to say whether or not you'd sign a bill that protects equal pay for equal work – you might have Romnesia. If you say women should have access to contraceptive care, but you support legislation that would let your employer deny you contraceptive care – you might have a case of Romnesia. If you say you'll protect a woman's right to choose, but you stand up at a primary debate and said that you'd be "delighted" to sign a law outlawing that right to choose in all cases – man, you've definitely got Romnesia.

Those who've already come down with Romnesia can be cured, Obama said. "Obamacare covers pre-existing conditions." Not surprisingly, Romney's camp wasn't laughing along with Obama and his supporters.

"America doesn't need a comedy routine, it needs a serious plan to fix the economy," tweeted Romney strategist Danny Diaz.

Since it's Friday, America seemed content to take the comedy and leave the economic fix for Monday: "Romnesia" quickly became the top trending word on Twitter worldwide.
