What Is The Meaning Of Club In Common? And Why Does I Only Can See It In Other fan Page?

It means..that toi and other fanpop users like the same things so there in the club too, and toi only see it on other users page not on you're page cuz it tells toi what clubs toi have the same as the user whom you're visiting their profile..if toi don't get it just wait for plus explanations

it'd called CLUBS IN COMMON what do why think it means?

Like someone else said, it shows the clubs that other people have joined that toi have also joined.

It's a way of seeing if toi have common interests with another user. ^^
