Tollfloof (floofinition) – housepet who blocks a common passage such as the stairs, a doorway, or hall, and doesn’t let others by without payment.
In use: “Dobie and Gillis were both tollfloofs. Both liked getting tolls paid on the top stair. Dobie offered his beagle belly for a rub as a toll. Gillis, though, turned on her amber-eyed target acquisition system and swatted anyone who dared to pass, but with her claws withdrawn.”
