To place your thumb on your middle finger
and place your other fingers on the hand on that finger
, then putting that in a variety of places for some one to look at.
Upon that person's looking you then fully open your hand and say "Got yo ahh."
Similar to "Made you look" but just telling them to look at your hand instead of an object somewhere else.
A zuping would be like this: say your sitting next to me and you ask me for a piece of gum, I then reach in my pocket and instead of pulling out a pack of gum I pull out a zupe.
