Polterfloof (floofinition) – A usually mischievous animal, often thought to be a ghost or apparition, held to be responsible for unexplained noises.

In use: “They thought it was a polterfloof banging on the window, because every time they checked the window, nothing was there. But the camera showed it was a young white cat banging on the window and then running away when they came out. With a little patience and kibble, they captured the little goof and gave him a home. He always continued his polterfloof ways, though.”
