1. Before it was perverted, it was a military manouver in which a soldier or a troop turn around in the opposite direction; 180 degrees.
"Charlie Company, A-BOUT FACE!"

*soldiers turn swiftly and uniformly to face the opposite direction.*

*Onlookers are amazed with such precision and sexyness...*

1. This position requires that the woman sit with her back to him. The male lies on the bed and the female straddles his torso, kneeling on either side of him. From this position she can put her hands on his knees, giving her the leverage to lift off. This position forces the penis into an uncommon angle, which many women find extremely exciting. If she wants to give him additional stimulation during this position she can reach down with one of her hands and massage his balls. Gentle pulling or massaging is often very desirable for men.

When walking down the hallway Adam must do the about face as he sees the girl from the party he kissed and no longer wishes to talk too.

The sudden 180-degree whiplash that the typical female teen pop star undergoes at a certain magical age. Her public/stage persona, until this time, accentuated her virginity, purity, and innocence. Suddenly, Daddy's little girl morphs into PowerSlut Girl, and her stage persona and performance incorporate pole-dancing, nearly transparent clothing, exaggerated sexuality, and raunchy language and content.

The Age 18 About-Face can be avoided by a singer who has genuine talent and is something more than a music-industry manufactured product, but realistically, how many female teenage pop singers fill that bill?
You know J. Random Teenie-Singer, that blonde Momon purity queen whose hymen seems to be worshiped by half the music industry? Yeah, there are a lot of middle-aged men slavering for a year from now when she pulls her Age 18 About-Face.
