What is govnokod and who are govkodery?

So many words about the heaps of govnokod and the crowd of govnokoderov. And I'm not in the subject.
I can not understand where the line between the freshman programmer, who is trying to implement their infinite ideas and govnocoder?
I can not understand, didn’t anyone of NOT shit coders ever write code that they looked through with horror, and why doesn't he call this code govnokodom?
