But then, Kochadaiyan literally means 'a King with matted hair' as Ko means a King and Chadaiyaan means one with matted hair. So kochadaiyaan would be king with matted hair.
And then, with that name, Kochadaiyaan is also used for Lord Shiva sometimes.
And that's the name of Rajnikanth's next film. Kochadaiyaan. Just in case you didn't yet know. :)
