The third gender of human beings. A spilkus or plural (spilki) can have male or female characteristics. However, spilki draw their power from their enticing, curly hair. Spilki are also easily recognized by their extreme awkwardness and love of running. Unfortunately, Spilki are extremely succeptible to injury. Spilki can mate with other spilki or themselves to produce spilkins (spilki youth). A group of spilki is called an Awkward.
