A catchphrase to counter to "once you go black" or repel the notion that Asian men are effeminate and lack the sexual prowess to please a woman.
Example 1:
Woman: You know "once you go black, you never go back..."
Asian Man: Well, that's because you haven't caught the fever because "there's no fever like yellow fever."
Example 2:
Woman: I don't know, I'm not attracted to Asians sexually...
Asian Man: That's because you haven't experienced the fever, because "there's no fever like yellow fever."
