A relationship where one person (usually the male) believes he will be getting lucky soon, but hasnt made any progress. The woman can make him do anything and has tamed him like a domesticated animal. The relationship is non existent and considered a partnership.
Person 1: "Why is he so pussy whipped? All he does is drive her around, buy drinks for her, and make her dinner. Are they dating?"
Person 2: "Yeah, has he hit that yet?"
Person 3: No, they're just in a domesticated partnership
