One who is duped into the teachings of abstinence-based sex ed. Some beliefs include the notion that oral/anal sex isn't really sex, that the human body is something to be ashamed of, that condoms cause cancer, that you can get pregnant by petting, that half of all gay teens have AIDS, that AIDS can be spread through tears, and the studies that show how ab-ed fails to curb teen pregnancy rates either don't exist, or are part of the evil liberal media conspiracy. Often self-righteous, holier-than-thou.
My friend told me that when she got married, her ab-edder friends wouldn't let her wear a white dress because it "symbolized purity" and she wasn't a virgin. I said she should've slapped their arrogant bitch asses.
