A male version of a chicken head. They don't know how to act, so they tend to act foolish.
Why are you talking to that boy? He's trippin, he is a dundahead.
It literally means 'dickhead'. It comes from 'dunda' meaning 'penis' in most Indian languages. Not to be confused with the Scottish 'dunderhead' which means stupid.
Donald Trump is such a dundahead.
