What the hell is a KOK? I know what a nuchal hump is, and I'm pretty sure its the same thing as a KOK. Why do people call nuchal humps KOKs? I mostly see that term in reference to flowerhorns. Wait a second, is KOK a euphamism for a male chicken? maybe not. just trying to figure out the diference between a KOK and a nuchal hump. How do you pronounce KOK, anyway?
