This is a person of asian race who has an (romantic) obsession with caucasian people. Usually white males who date asian women are accused of being asiaphiles. We ask the question - what about the women?
Vickie Chang of the OC Weekly accuses Orange County men of being asiaphiles, though never explores an asian womens obsession with dating white men. We like to call them caucasiaphiles.
Men (or women) of Asian or African origin who show particular sexual interest in white women (or men).
He's always chasing white girls, one over the white man I suppose, such a caucasiaphile.
