look up any word, like donkey punch:
 
1.
n. A woman's staunch dedication to abstinence before marriage, or a reference to her "enrollment" in the Iron Hymen program.

n. A parody website, URL ironhymen.com, sister site to sexisforfags.com, perpetrating to be part of the White House's Youth Purity office. It lists an oath that one must take and follow to stay abstinent until marriage. They also sell cool t-shirts.
Watch out, boys! Thanks to Iron Hymen, you ain't NEVER gonna get inside my baby cave!
