Derives from the old fashion way of coming up with a person of color's name for there kid. Done by throwing a fork up into there and hearing the sounds that it makes. Thus creating the name Kachinka.
"What do you think we should name our kid? Throw a fork up in air and see the sound it makes! Ok. KACHINKA!"
Evil child who is a spawn of satan
Kachinka will eat your soul and hiss at you.
