The medical condition when one is so sexually attracted to a black woman that he will throw himself onto her in a sexual rage that cannot be stopped by any force on the face of this god given free land.
Mike: "God dammit wei, i thought i told you to control yourself when we are walking on the street. You always go nuts when a black chick walks by, this is the third time you've taken your cock out and asked her to jack you off like a goddamn baboon."

Wei: "Ahh man come on. I just have that Chris Ryan Disease. It's a medical condition and not my fault. When i see a black girl, this sexual urge comes over me and i can not control myself."
