Body condom, what???

Here's one for ya. I knew this person who had gotten engaged, and they were very "excited" about the wedding, if you know what I mean. They had gotten pretty close, maybe a little too close, and they just loved each other so much, that they needed to take precautions. I think you're all getting my drift. So...what is the most logical thing they could've done? Apparently it was going out and buying a leotard for her, to protect them from doing anything! Haha. The best part about it, is they got so excited about their idea that they ran to the store together, to find the perfect leotard. And the "logical" explanation behind this was that if there ever started to be any wandering hands, he would feel the leotard, feel stupid, and that would stop them from doing anything they shouldn't. Wow...I was beside myself when I heard that. And...I took it upon myself to call it the "body condom". Any other names you guys could come up with for this one??
