facebook fan-addict
A Facebook fan-addict is someone who will join any page just to see what's inside, even if it means getting yelled at by Facebook for being too much.
'I joined 'The Secret Life of Cereal' because I had to know what it was about.'
My cousin joined 'The Hug Life' just to see if it was worth it.
I joined 'People Who Can't Decide What Time to Post' because I wanted to know the answer.
