Movie: Nautanki Saala
Music, Lyrics and Singer: Falak Shabbir
Tujh se hi to milee hai raahat
Tu hi to meri hai chaahat
Tujh se hi to judi zindagi
Teri yaadein hain kuchh adhoori
Saans aadhee hai kuchh hai poori
Aankhon mein hai kaisi ye nami
I have got peace from you only,
you only are my love..
To you only my life is attached..
Some memories of yours are incomplete..
Even my breath feels incomplete (without you)
How's this wetness in eyes,
Nautanki is a traditional, popular form of Drama in India and some other parts of Indian subcontinent. A nautanki is generally full of songs and dances and even dialogs can be in form of songs many times. Hence, the drama form is considered to be a loud one and hence, when someone is called a nautanki, it basically means they're overtly dramatic.
So the phrase 'Nautanki Saala!' would be a slang, calling a person overtly dramatic, in a casual way.
