Get the Wingnut mug.
A name given to a person who has ears that stick out the side (at a greater angle than is usual) like little wings on their head. Sort of reminiscent of those little nuts that are easy to screw because of their wing-like attatchments, also called "wing nuts".

This is how it is used by some people in New Zealand anyway.
