Virgin Slut Factor n. (vûr j n sl t f k t r) or VSF
The mathematical theory that the number of years one waits to have sex is directly proportionate to the freak level they will attain after copulation. For Example if the going age in your area is 17 and you wait until you are 18 you will probably only have one partner during this first year of discovery. Unlike the one who might wait until they are 27, who might feel that they need to make up for lost time therefore sleeping with 10 people in the first year.
It isn’t Brittany’s fault that she is a total hoochie, her VSF was just too high.
