Get the Mad Doggedmug. Maisie, commonly referred to as "mad eye", is the name given to one distinct ginger. Often noted for her sudden interest in hand gestures along with the usage of two Italian words., the name Maisie actually means "Greek Margarita". Also known as "Kelly", mad eye is truly versatile in what she can accomplish and therefore is destined to become a spy for the CIA and USSR. Mad eye Maisie can be spotted out of a crowd due to her ginger hair(described as a rose in Goolia's famous poem) that is often paired with a nonchalant hair clip.
