like it says, its a bookmark. when you click on your profil pic. you will see: homepage, timeline, BOOKMARK, setting and logout. and if you click on bookmark you will see; "my bookmarks on mangago"
Man like 5 seconds after I asked this question I pressed my pro pic and realized what the bookmark was for. LOLOLOL!!!
