"I think va-jay-jay is a nice word, don't you?" Oprah asks. "Everybody who watches Grey's Anatomy knows that's where we got that from."
One audience member announces that she and her sisters call their private parts "nunu." "My nunu's name is 'Lavender,'" she says. "I thought I'd share that with 30 million people."
Leave it to children to come up with another hilarious nickname! "My daughter, who was 2 years old at the time, told her dad she couldn't go to the bathroom because she didn't have a peanut like him...but she had a piñata," says another audience member.
