A twatwaffle is a person, regardless of gender, who is basically so ignorant of their surroundings as to require a seeing eye dog to find their own nose. Incapable of making rational decisions, and having no regard for their fellow human beings. Generally a lowlife type, with the addition of being a megalomaniac.
That idiot who ran the red light and almost hit us is such a twatwaffle.
