The girl you have a summer fling with who lives next door to your parent's house in Cape Cod. Your Cape Cod girlfriend exudes versatility. She can tear up the tennis courts and be the best-looking girl at Red Lobster. Unlike the manic pixie dream girl, your Cape Cod girlfriend keeps things grounded, despite her (optionally) affluent background. She's the the best girlfriend in New England. Famous examples include Jane Gallagher, Joey Potter, and the subject of " Cape Cod Kwassa Kwassa " by Vampire Weekend.
