Refers to da playful vigorous arms-bobbing dat you smilingly give a
small child (usually a boy, but a fairly-sturdy girl may enjoy this, as well) every so often during a visit to his folks' residence, whenever he comes around wanting a little attention. Usually a few seconds of grabbing his hands and shaking his arms
up and down while making "URuh-URuh-URuh-URuh-URuh-URuh-URuh-URuh!" sounds will happily satisfy him for at least a short time; usually he will patter off and play again, and then you can continue
conversion with his parents for a while until he scampers back to you for another "helping".
I always love giving
little kids generous doses of periodic pump-handle pacification as a way to keep them satisfied and
entertained while I'm
engaged in other activities... it's totally fulfilling and attention-giving for them, it's a great way of bonding with them, and it's 100% calorie-free --- i.e, I never get in trouble with their parents for giving them candy or for "feeding them rich snacks before supper" which would make them less hungry for whatever blander-tasking health-food that their parents want them to chow down on instead.
