A new song from director Rajkumar Hirani's film "PK" is out, and its called "Nanga Punga Dost." In the song Anushka Sharma calls Aamir Khan a "tinga tinga nanga punga dost (short and naked friend)."
The song is composed by Shantanu Moitra and the lyrics are by Swanand Kirkire. The composition itself is not very exciting, and probably will be liked only once it is seen in the context of the film.
The video is surely intriguing, with Aamir going about town displaying various antics as Anushka follows him around to observe his behavior and understand him.
