#9. Vajayjay

How can we possibly write about this in a dignified way? Well, it's funny, foolish slang for "vagina." Yes, we can print that. The term, popularized in 2006 by Grey's Anatomy and more recently by Oprah Winfrey, is fairly indicative of where we are linguistically as a nation. Borne out of a network's fear of mentioning an anatomically correct word too frequently during a primetime medical drama, "vajayjay" demonstrates that in some ways, Americans are still immature about many things, including penayays.
