Fanboys, are usually a rare species. Usually, a boy that tweets their idol 13,927,734 just to be noticed. Also, at least knows all the OTPs possible and especially their birthdays. Keeps every picture possible of their idol, and usually either owns a fan page or co-owns one, very similar to a fangirl and has the ability to instantly bond with a fangirl or boy. But most important their AMAZING people if you find one hold them tight because you won't find many.
