an absolute wanka of a person, even more extreme than being just a "tool" or a "big tool". being called a major tool is one of the worst things that can ever happen to you. if you do get called a major tool its best to hide under a rock.

greg: you don't mean that
johno: be quite assclown, go hide under a rock
