look up any word, like sex:

Fankids are children of two parents: An official character from a movie, book, show, video game, etc. and a fancharacter.

(see fanxofficial)

Fankids are usually children of hetero fanxofficial pairings (for obvious reasons) and are often flamed just as cruelly as the fanxofficial pair they come from.
I created a child, or, a "fankid", for my pairing Demyashaa, a pairing involving Demyx from Kingdom Hearts II and Ryashaa, a character I created.
