A profound and controversial characterization of the female genitalia, where "Ditch" represents the angular, contoured bordering meat of the labia, and "Squid" depicts the amorphous, unidentifiable, moistened nonsense in between. Sometimes used as the final closing/mic drop term in adolescent "funny names for genitalia" competitions.
