what does it mean to be in a fandom
Fandom Fandom is a subculture composed of fans characterized by a feeling of empathy and camaraderie with others who share a common interest. Fans typically are interested in even minor details of the object(s) 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 (a fandom); this is what differentiates "fannish" (fandom-affiliated) fans from those with only a casual interest.
Trip the light fantastic (phrase) The idiom "to trip the light fandango" was already in usage in the US as a phrase for carefree dancing in a Spanish or Latin American fandango style by the time of World War II (see, for example, its usage in the recording "South America", Vitaphone Release 1460A, 1945).
