Subfloofidant

Subfloofidant (floofinition) – Placed or occupying a lower class or rank, or considered an inferior position to an animal, particularly a pet.

In use: “Samantha always felt she was subfloofidant to her husband’s dogs — he had two — but he’d had them before he’d ever met her, but then he had to go away on business, and suddenly she and the dogs were having a love affair, and, well, the dynamics were pretty different after he came back, with him now living as the subfloofidant one.”
