A tool used to protect stupid people from invisible rain. It is most commonly used in hot weather. Usually, the hotter the weather, the more likely it is to spot someone using one. If you do, please yell, "It's not raining, ya douchenozzle!"
Oh, dear--is it raining nothing again? Better get my parasol out to protect me from the invisible rain that only stupid people can see.
