verb. playing around, goofing around, fidgeting, playing with objects. mostly used with children. I first learned the word in the mid 60's. We heard it our household all the time growing up. to be cute you can call someone who gribbles a lot, a gribbler. gribbling can also be an annoying thing. if one child is poking another child on a car trip, you might turn and shout "hey! stop gribbling or you'll walk home"
example with gribble -- 'Stop gribbling I'm trying to watch this show!'
