Fameproof

3 uses. 1. Impervious to fame. As in doesn't let popularity go to one's head. A celebrity who doesn't act like a celebrity. Not pompous, stuck up or conceited. 2. Unable to achieve fame. Such as someone who is so devoid of talent, class, standing or ability that they will never achieve fame. 3. Someone who is so beyond the norm as to be beyond the aptitude of fame. Someone who is too controversial, too far out, too beyond the average to get accepted in the main stream. This would be the opposite of the 2nd usage in that the assumption here would be that this person has too MUCH talent to be famous, as opposed to too little.
