Derived from highway, it means a path in a crowd where many people pass through, e.g. on parties. One should use crowdways to go from point A to point B to annoy the least possible amount of people.
"We need to find a crowdway to get to the nearest bar."
"Damnit, we're standing on the outskirts of a crowdway, let's go find somewhere else to stand."
