This is simply the act of using your hand as a kleenex during awkward times where any kind of tissue/toilet paper/paper towel/gum wrapper is nowhere to be found. The handsnot is then wiped on something else, usually one's sock.
Man, I had a cold last weekend at Bertha's parents' cottage and pulled a handnex right in front of her grandmother. She handed me a used maxi to wipe it on, what a saint.
