usually associated with male caucasians who haven't yet been laid or haven't gotten up to any level sexually. guys who've been 'diagnosed' with yellow fever are always befriending asian girls, then asking them out after only a week of getting to know them. usually the guy can be extremely attractive, and the girl, unknown to the fact that he sweats her for only her ethnicity, will accept the relationship because he seems extremely nice.

actually, if the asian girl happens to be pretty traditional, you know, is really into the asian pride thing, speaks their parents' tongue, still has an accent, is kind of tacky, etc. they'll never get that the guy has yellow fever. because it's kind of hard to explain this disease to them...they're dumb. some of them.

now, if the asian girl was raised in america, and doesn't speak her parents' tongue, doesn't have an accent, but still respects her heritage and is just a normal member of the crew, BUT in some cases would be wrongly labeled as a twinky by really ignorant folk will soon realize his sickness once she goes to his myspace page and finds that he 'collects' asian girls across the globe, or sees his immaculate amount of asian friends at school. she'll then see that he has been disgustingly endowed with a horrible case of the disease.

*a list of the reasons WHY yellow fever guys are obsessed with asian chicks:
1. the well-spoken stereotype that all asian women are horny and sex-craving has the guy thinking that if he gets an asian girlfriend, they'll be groping 24/7. not true. ALL girls are like that.
2. the naive manner from traditional asian girls, examples: easy to persuade, easy to woo, shit like that. those guys will think it's going to be extremely easy to get her. and the div girls will make it easy. stupid. mostly not true. ALL girls are like that.
3. the exotic-ness of them. which is nice in a calm way, but then when they distort it and are like, woo! tanned skin, tight pussy, jet black hair, woo! ALL...uh...anyway...

BUT as with the usual ho-hum definitions of this term, it can also mean obsession with such things like, dance dance revolution, japanese media, anime, gaming, anything that is connected to the asian network.

okay. i'm done. to all the yellow fever dudes, a few words: get a life, lol.
(checks myspace...)
1: 'what the fuck!'
2: 'what?'
1: 'these fucking asian obsessed sick bastards, look! nothing but asian girls on his friends' list. i'm not a fucking trophy to be added to his fuckin' collection. and also, he's like fucking 40...'
2: 'yeah...annoying!'

asian girl 1 (really cocky, high-pitched voice, annoying accent): OMG. did i tell u?
asian girl 2 (normal): no, you didn't...what?
asian girl 1: i hav a new boyfrend!!!
asian girl 2: wow! congratulations! who's the lucky guy? :)

An affliction the webmasters at Urban Dictionary seem to have an acute case of. Reload their front page 10 times, and I bet a different asian girl pops up 9 times.

1) A disease carried by mosquitoes in tropical regions, especially in South America, Africa, and the Caribbean. Symptoms include sudden fever, yellowing of the skin, and hemorrhaging. A very dangerous disease that is quite often fatal. It was the number one cause of death for Americans during the construction of the Panama Canal. Nowadays a yellow fever vaccine is required if you're traveling to said tropical regions, especially during the summer.

2) When a person of non-Asian ethnicity has strong feelings and/or urges of an Asian person of the opposite gender. Usually these urges are sexual, but not always. Wasn't too widely known until the release of Harold and Kumar Go to White Castle.
1) Good God that vaccine hurt! But I guess it's better than dying....

2) Little Billy went to a club in Chinatown and now has a sudden case of yellow fever.

When a white male has an excessive attraction towards females of the Asian persuasion regardless of how FOBISH or jacked up looking the girl really is; he’ll still think she’s the most fuckable thing on the planet. Also, they know nothing about the girls culture, can rarely tell the difference between any nationalities, think they all fuck like the girls they see in porn and never heard of Laos until King of The Hill.
Fevered: dude, I wanna fuck Trang!
Friend: are you kidding me? She’s missing half her teeth and is built like a 12 year old boy! Plus she barely speaks English! man! You’ve got yellow fever!
