It is not an appropriate word to describe "Ganeshmaan Singh" a national figure in such a chhudra word. Of course, he was "Hulyaaha" or one of the of some nughty guys of in his tole, known as Hira Kaji. It doesn't mean than he was "Gundaa" . Moreover it was the episode of his teenage time. If some one used to have "Singaan" in childhood, you can not address him/her as "Singaane". Respect to the senior and respect the figure who was admired by the majority of people. You if don't like him. do not mention his name in bad sense or in good sense.
