Vatican roulette

Vatican roulette

1. slang A method of birth control in which heterosexual partners do not engage in sexual intercourse while the woman is ovulating; more commonly known as "the rhythm method." An allusion to contraceptives being banned within the Catholic ideology (the governing body of which is the Vatican) and the fact that the effectiveness of such a method is as much a gamble as playing roulette. In this day and age, and with four children already, I find it mind-boggling that you and Sarah would be playing Vatican roulette to keep from having another baby. My periods have always been unpredictable, so I've never trusted Vatican roulette as a potential method.
2. slang A method of birth control in which a man withdraws his penis from his partner's vagina before ejaculating; more commonly known as "the withdrawal method" (technically called "coitus interruptus"). We got so caught up in the moment that I didn't bother asking if he had a condom, so I just told him to pull out before he came. Well, suffice to say that we lost that game of Vatican roulette.
3. slang Heterosexual intercourse in which no birth-control methods are used at all. Why on earth would you not use a condom, dude? If you go playing Vatican roulette with every girl you hook up with, you're going to end up with a baby in your arms before you've even graduated college!
