Someone who is popular because they are connected to a object or a cause, however they quickly lose their popularity when the object/cause is gone.
The guy you might find in a beachside bar, with a Parrot perched on his shoulder. The guy is very well known because of his pet bird, and is the life of the bar. However, after the Parrot is gone, the guy is found uninteresting without the bird.
