Melanfloofy (floofinition) – An animal who expresses a state of sadness without discernible or apparent reason.
In use: “The big golden red retriever seemed melanfloofy, showing little interest in going for a walk, which was definitely abnormal. Head resting on his front paws, he settled in his bed and stared out the front window for most of the morning. Then a cat walked up and peered in. Tail thumping his bed, Red leaped up. Melissa concluded, my dog is in love with a cat.”
