The region in which one "motorboats" or more colloquially, the space between two breasts on a woman. This region previously had not been named and thus derives its name from the common action of placing one's face in between breasts and imitating sounds of a motorboat. Because boats dock in a harbour, this region is referred to as the harbour.
Hey girl, is there room for one in you harbour?
