negative body count
A body count of zero means that one is a virgin. Having heterosexual encounters to the fourth-base degree increments one's body count while having homosexual encounters of a similar nature decrements one's body count. Thus, someone who has slept with five men and five women is *technically* a virgin.
Vinny's body count is a large natural number whereas Sean's negative body count requires a sign-bit to store as a 32-bit integer.
