Sure, there are countless words for getting it on, but very few of them could be described as "classy." Thankfully BuzzFeed has rounded-up some lesser-known adjectives, nouns, and verbs to take the place of our usual crass euphemisms and romance-novel descriptors. For instance, did you now that "perfectly shaped buttocks" can be described as callipygian? Sounds a lot nicer than "nice ass," doesn't it? Or that "the bobbing or jiggling of a woman's breasts when she walks, dances, or exercises" is known as mammaquatia? No, you probably didn't.
