From Ancient Greek κόρης (kores, gen. of girl) + φίλος (philos, love), coined by analogy to paedophilia.
Can have any of the following closely related meanings:
1) A paraphilia in which an adult's primary sexual attraction is towards prepubescent girls.
2) More generally, any sexual or romantic feelings or desires directed towards prepubescent girls.
3) Any sexual act by an adult towards a prepubescent girl.
Korephilia is one of the most universally condemned sexual orientations in the world today.
Peter Griffin: This is almost as bad as that time I thought I had korephilia... *humorous flashback*
