Lexicographer and slang expert Jonathon Green has been producing a series of timelines based on his comprehensive historical dictionary of slang, Green’s Dictionary of Slang. He recently added timelines for vagina and penis. (If you don’t see any words on the timelines, zoom out using the bar on the right.) They show that metaphors based on weapons and food have always been popular and that vulgarity is nothing new. There is a great deal of human creativity on display in this domain, especially when it comes to the most polite terms. Here are 35 of the classiest sounding slang terms for vagina and penis from the past 600 years.
