Wanna "play at rumpscuttle and clapperdepouch"? No, that's not from a New York Times trend piece; it's off this amazing list of historic slang terms for sexy times, compiled from Green's Dictionary of Slang by the wits at Mental Floss. Sure-fire crowd-pleasers include: "playing at couch quail" (1521) and "fadoodling" (1611). "Joining paunches," circa 1656, is my personal favorite.
