You can't make shit like this up. The woman wears the protective condom like a tampon, and if she should happen to be raped, the condom attached barbs to the offenders junk. The barbs can not be removed by anybody but a doctor, making identification of the rapist likely to happen at the hospital. It doesn't actually prevent the rape, but it sure does make it easier to catch the animals responsible.
Now, In my research I found that they have been developing this condom since 2005, and have distributed 30,000 of them free of charge in South Africa during the World Cup in an effort to curb the amounts of rape during the overcrowded tournament. So while the movie did not actually inspire the condom, I am glad that it is accomplishing the same goals... no means no, and if you rape someone I hope you are prepared to lose Mr. Winky forever...
