RAWESOME: n, Mainly SOMEONE, A PERSON (*but can apply to a Group, or even Something) that intrigues, excites, exhilarates, bewilders and "goose-pimples" an onlooker's eyes and senses with their unique originality of self, speech or special physical attributes and/or physical abilities, i.e., sports, etcetera.

"...Oh, my God!! Isn't THE GUY that invented THIS WORD, some kind of RAWESOME!!?" or, "Good Lord--did you see that?! She just did a double-forward, 2-1/2 pike into a backward triple sow cow and into an impossible Jericho Loop!! Now is she RAWESOME or what?!?"
