You do know that the kok is pronounced "coke" right? Not to mention in American it's perfectly fine to be *** so I don't know what your problem is unless your a homophobe.Its stupid and verrrry off-putting to people who speak the english language.
Its a nuchal hump or head. It was that before it was ever a "kok". Take your kok talk to Thailand where it isnt lost in translation and appearing as a homosex invitation.
