Phenomenon common in diversified cities where Caucasian, African-American, or any race other than the Asians become obsessively interested in Eastern asian cultures (e.g. Chinese, Japanese, Korean)
The expression of such interest is most commonly expressed as having an Asian partner (girlfriend, boyfriend, spouse), being obsessed with anime and cosplay, as well as other popular Asian medias (Kpop, Jrock, Dramas and so forth.)
Also linked with the term Yellow Fever
Known for its parody effect for its similarity with the common vaginal skin infection: yeast infection
Alice was so in to the popular Asian cultures, she drowns herself in anime, cosplay and even her boyfriend was asian. She obviously has the case of an east infection.
Whenever David saw a Caucasian male with an Asian female, he would say, "That guy definitely has an East infection."
