Catholic roulette

slang

1. 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 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 Catholic roulette to keep from having another baby. My periods have always been unpredictable, so I've never trusted Catholic roulette as a potential method. A: "We just won't have sex when I'm ovulating next week." B: "What if your period app is wrong, though, and you're ovulating now? This is why you can't depend on Catholic roulette."

2. 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 Catholic roulette. You know, there's still a chance she'll get pregnant even if you pulled out. That's why they call it Catholic roulette, bro. Like he's really going to be able to pull out in time? Yeah, I don't recommend that game of Catholic roulette.

3. 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 Catholic 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! I have no interest in having a baby just yet, but I also don't want to go on the Pill, or play Catholic roulette, so I'm abstaining from sex altogether! Yeah, I did a lot of dumb things in college, but playing Catholic roulette wasn't one of them! I had a serious girlfriend, and we always used protection.
