Fandom (consisting of fan [fanatic] plus the suffix -dom, as in kingdom, freedom, etc.) is a term used to refer to a subculture composed of fans characterized by a feeling of sympathy 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.
I was asking about my daughter's obsessional interests in all things Marvel (movies, comics etc.)
She siad she figured she got her "Fandom" from me and my Tesla interests. OF COURSE I denied it and said this was something completely different :o)
