Oxford Dictionary says the word 'Mega' means brilliant, excellent, enormous; and 'Megalomania' means a mental disorder producing delusions of grandeur, a passion for grandiose schemes.
Well, but for Telugu people 'Mega Star' means Chiranjeevi. Though he achieved a lot in his life, he never boasted that the entire film industry is rotating around him. He always maintains his modesty in public life.
But Pawan Kalyan feels that he is the Nucleus of the film industry. He talks in such a way that if something pains him, the entire industry should feel the pain. He feels himself bigger than anyone else. This mental disorder is called 'Megalomania'.
So, since Pawan Kalyan implied that he is not comfortable with the title 'Power Star' in the 'Republic' prerelease event, he can be comfortably given the title 'Megalomania Star' without any dispute as it suits his personality perfectly.
What incidents show Chiranjeevi as Mega Star? and what talks show the megalomania side of Pawan Kalyan?
