A snurfle is the complex action whereby you rub your face back and forth into the sleeping tummy (i.e. snurf) of, for example, a sleeping cat or kitten, making snuzzle noises for the entirety.
The twist is that you then concomitantly lift both the head and rear of the animal effectively creating a panoramic mask of snurfability. Obviously this would exclude the commonly snuzzlable human element, though this author certainly would not discourage you from trying.
Theoretically this action could continue indefinitely, although the duration will only be equal to the patience of the cat or animal in question, with a drastic reduction thereof in comparison to a standard snuzzle.
