The act of purchasing an ice-cream cone at a drive through, asking the person if they believe in unicorns, then sticking the ice-cream cone to your forehead while slowly driving away screaming, "believe"!!
Mary and Jane went uniconing through the drive-through window with icecream cones stuck to their forheads.

Amy and Sandra went uni-coning at mcdonalds, getting ice cream all over their faces!
