Stephanie Rosenbloom of the The New York Times has an excellent piece about the word "vajayjay," a euphemism for vagina coined on "Grey's Anatomy" and popularized by Oprah Winfrey.

There was some gnashing of teeth on Wordie when vajayjay was first listed a few months ago, but the word fills a linguistic void, according to Rosenbloom: There are a slew of lighthearted euphemisms for male genitalia (enough to constitute a Monty Python song), but fewer for the female equivalent, and fewer still that aren't vulgar or sexist.

Rosenbloom takes a silly word as an occasion to talk to some serious linguists and writers on some interesting topics. Well worth the read.
