While Grant Peterson may have coined the term "S24O" for a sub-24 hour overnight bike trip, I think it is time to expand the taxonomy of this type of touring. For example, when I don't camp and rely on the plastic, I think that is a "CC-S24O." I am planning a trip where my wife will meet me to the spend the night in an interesting city on the second day (and drive me back home), which will be a S24O-W. And some of my trips that were just ill-conceived or doomed from the beginning? Those will be known as S24O-WTF's . Other ideas??
