I've stolen the word Superbeast from Teletext, but it deserves a mention since it is one of my favourite words.
Indeed, it's not really a word, more a concept. After all, can words have numbers in them? I think they should be allowed to if they want. The Superbeast is a kind of abstract way of describing emptyness in the pop cultural wasteland of modern day nothingness.
Also, once in a business studies class I managed to convince our teacher that a creature called Superbeast 47 had been developed in a laboratory!
