During gift-giving times in our home, we often refer to "the box ripper." This is not a person.
A box ripper is when you start to casually open a gift and suddenly realize that beyond your wildest expectations someone bought you that special thing you really wanted. All you have to do is just get the box open, and it's yours. (A famous one in our house is a Christmas gift I once received of a full-length coat with lamb's wool collar and cuffs.) The subsequent excitement may lead to rapidly torn paper, shrieking, fast-talking, many big grins—and hugs. Lots and lots of hugs.
Of course, our family has acknowledged that finding, affording, and buying said box ripper—every time someone gives a gift—is not always possible or feasible, which may be why those types of gifts are so very exciting.
Sadly, many of our family gifts these days come in the form of 2x3 plastic cards with a store logo on them. Not my idea of a box ripper, though sometimes more appreciated than a size-too-small sweater or a tchotchke designed to sit on a shelf. I still always try to give at least one non-gift card item for each family member to open. It just doesn't seem right to only exchange pieces of plastic, no matter what their monetary value.
