yellow fever
A mental condition often found in white males that is characterized by a ferocious apetite for girls of asian descent. Symptoms may include a fascination with Hello Kitty, japanime, Domo, Mr. Chu's Asian Beaver, Japanese culture and language.

In severe cases, an individual stricken with yellow fever can be referred to as a "Wapo", and may harbor a twisted interest in Asian inbreeding, which causes bow-leggedness. Some Wapos may date Mexican girls in between Asian girlfriends due to limited availability of FOBs in a given community. Wapos may also claim to be improving Asian standards of living by offering a larger penis size, which is usually an obvious lie.

Those with yellow fever also seem to unconsciously detect an Asian girl's prescence, generally within 10-15 meters, and refer to it as a "Code-Y" (comp. "Gaydar").
"Wow, Chris has a bad case of yellow fever. He's almost as bad as Mr. Chu."

"I'm not gonna lie; I've caught the yellow fever."
