A drinking game where a couple must perform positions in the Kama Sutra in the backseat of a car within 20 seconds and are judged by the other passengers in the car. An unacceptable stance results in the couple taking a shot of alcohol, while an acceptable stance results in the remaining passengers taking a shot.
Man, who wants to play a few rounds of Backseat Sutra?!
