Misfloofievous (floofinition) – irresponsibly playful housepet; a housepet who’s playful in a naughty, teasing way.

In use: “Smart and misfloofievous, the black lab quickly understood the people’s patterns and habits. Being people of habit, they retired to the den to watch television in the evenings. As soon as one went that direction, she raced ahead, found the remote control, picked it up in her and began a game of keep-away. She was always pulling floofnanigans.”
