I don't know if there is a technical name for it, but I call the grip you describe as the "fist" grip. I see it used almost exclusively by females and I have speculated that it is motivated by the force required to make legible marks with cheap ballpoint pens. I noted that the boys in those videos were all using the standard "tripod" grip.
