A person chooses two Bollywood things in a pair, such as, two movies, two songs, two actors,or two actresses etc....The next person chooses the one they prefer and then lists a pair for the next person and so on....
EXAMPLE:
Kareena or Bipasha
The next person chooses either one they like and lists another pair...
Kareena
TUM BIN OR DHOOM
So you answer which one you like more and list another pair for the next person...
