Fandom has its roots in appreciation for sports.
 Fans typically are interested in even minor details of the objects of their fandom and spend a significant portion of their time and energy involved with their interest, often as a part of a social network with particular practices, differentiating fandom-affiliated people from those with only a casual interest
 Fans use gifs to show how they feel about characters or events in their fandom; these are called reaction gifs
