The thrust-to-bust ratio is a rudimentary yet effective measure of sexual performance.

The thrust-to-bust ratio can be calculated by dividing the number of in-and-out cycles performed in sexual intercourse (known as the thrust, or T) before nutting by the number of nuts busted during sexual intercourse (known as B).
Hey baby girl I've got an average thrust-to-bust ratio of 140/1 you should come over to mine sometime ;)
