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.
