My new favorite word: interdigitation. Especially when its overheard as "premarital interdigitation". It essentially means holding hands- fingers entwined- but it just sounds like it should mean something dirty doesn't it?

That was close to one of the first things a certain *coughdavidcough* person said to me... thus, the "defenestration" thing.

Him: "Do you believe in post introductory, premarital defenestration?"

Me: "Do I believe in throwing my future spouse out the window after I've met them? Sure!"
