Pop: Verb. To cause (something) to burst, making such a sound.

I have no idea why anyone would wait until they're nine-ish months pregnant to start making the rounds as a social butterfly -- but in the past week I've seen more pictures of Melissa Joan Hart than Britney Spears and Paris Hilton put together. Now I'm not saying pregnant women should be "hidden away from society," if you will, until they're ready to be rushed to the hospital under the cover of night to go into labor. But when girlfriend looks like she's gonna pop right on the red carpet, maybe it's a sign to sit this one out. I'm pretty sure it's still a faux pas in Hollywood to break your water all over a pair of someones Givenchy heels.
